The `xxx_ipv6multicast` function in each driver is not adapted to
multiple IPv6 addresses yet, and they're redundant, so try to take them
into common code.
Change:
1. Add MAC `g_ipv6_ethallnodes` and `g_ipv6_ethallrouters` in
`icmpv6_devinit` and call them in `netdev_register`
2. Add multicast MAC for Neighbor Solicitation when adding any IPv6
address, and remove them when IPv6 address is removed
3. Select `NET_MCASTGROUP` when `NET_ICMPv6` because now we need
`d_addmac` when we have ICMPv6
Note:
We want modules outside net stack to call functions like
`netdev_ipv6_add` and never touch the related MAC address, so these MAC
functions are added as internal functions to `net/netdev/netdev.h`

This commit sets the BLE's interrupt as a IRAM-enabled interrupt,
which enables it to run during a SPI flash operation. This enables
us to create a cache to off-load semaphores and message queues
operations and treat them when the SPI flash operation is finished.
By doing that, we avoid packet losses during a SPI flash operation.
This commit provides an interface to register ISRs that run from
IRAM and keeps track of the non-IRAM interrupts. It enables, for
instance, to avoid disabling all the interrupts during a SPI flash
operation: IRAM-enabled ISRs are, then, able to run during these
operations.
It also makes the code look more similar to the ESP32-S3 SPI flash
implementation by creating a common `esp32_spiflash_init` that is
responsible to create the SPI flash operation tasks. The function
intended to initialize the SPI flash partions was, then, renamed to
`board_spiflash_init`.
Whenever we enter/leave a critical section, the interrupt status is
saved and, then, restored. However, for the ESP32's BLE adapter,
entering/leaving a critical section is done on separate functions
that need to be registered as a callback.
The status flag was being saved as a global variable. However,
calling nested enter_critical_section would overwrite this global
variable that was storing the previous flag and, when leaving the
last critical section, the restored status would be different from
the one expected. The proposed solution for this issue is to create
a global array to store the interrupt status flags for nested calls.
When ESP32's BLE is enabled, select the option to pin the HCI TX
thread to a specific core. This is necessary to avoid problems
with the BLE task that runs pinned to the PRO CPU (core 0) while
running with SMP enabled.

or long time data transmission.
The spin_lock in the wlan_recvframe() function that receives
RX data packets from the wireless network card and the critical
section lock in the iob_remove_queue() processing are nested,
which causes the interrupt to be disabled for a longer period
of time, resulting in a risk of deadlock.
When we build NuttX on macOS, it shows many `sed` messages (and the build still completes successfully):
```text
$ tools/configure.sh pinephone:nsh
$ make
sed: illegal option -- r
```
This is due to the Makefiles executing `sed -r` which is not a valid option on macOS.
This PR proposes to change `sed -r` to `sed -E` because:
- `sed -E` on macOS is equivalent to `sed -r` on Linux
- `sed -E` and `sed -r` are aliases according to the GNU `sed` Manual
- `sed -E` is already used in nuttx_add_romfs.cmake, nuttx_add_symtab.cmake and process_config.sh
It looks like we do not need to send the 9 clock ticks whenever we reset
the FSM. We are already doing this in i2c_reset function if necessary.
This makes the i2c transfers much faster, for example the i2c(-tool) dev
scan feature.

In order to gracefully stop the I2S stream, add an interface to set
a `streaming` status variable that sets the `AUDIO_APB_FINAL` flag
that will be handled by the upper layers of the audio subsystem.
According to RX/TX operation, the DMA descriptors (inlink/outlink)
should be set differently. When setting the inlink, the `suc_eof`
field must be cleared by software (it will be set by hardware when
a packet is received). Similarly, the `length` field will be set
by hardware a packet is received.
Define macros used to access the registers of the GDMA channels
according to the selected channel in the header file, enabling them
to be used by other drivers.
By splitting into two different functions the setup of the DMA
descriptors and the action of loading it to the GDMA outlink
register, it enables us to "cache" DMA descriptors ready to be send
and, then, just load them whenever we are able to actually send it.
The macro `SET_BITS` only sets the bits according to the bit mask
and, once it's being used to set the address field of the GDMA
inlink/outlink register, it's necessary to clean all the bits
corresponding to that field that were eventually setup previously
to avoid messing with the bits that correspond to the current
address being setup.
Considering kernel code, it's reasonable to use `PANIC()` instead

ESP32-S3 has only one 2.4 GHz ISM band RF module, which is shared
by Bluetooth and Wi-Fi, so Bluetooth can’t receive or transmit data
while Wi-Fi is receiving or transmitting data and vice versa.
Under such circumstances, ESP32-S3 uses the time-division
multiplexing method to receive and transmit packets.
The low-level Wi-Fi driver registers two peripheral interrupts to
the same CPU interrupt. Although the registered ISR is the same for
both peripherals interrupt, it's needed to call `up_enable_irq` to
ensure that the interrupt matrix is being set accordingly.
Please note that the current implementation of the ESP32-S3's IRQ
driver - although allow us to set a callback for each IRQ, which
represents the peripherals interrupt - doesn't allow us to call
both callbacks when these IRQs refers to a same CPU interrupt.
`g_cpu0_intmap` (or `g_cpu1_intmap`) associates each CPU interrupt
to a single IRQ/peripheral and, then, when a CPU interrupt is
triggered, only the last registered IRQ's callback will be called.
This isn't a problem here because 1) the registered callback is the
same for both IRQ's (in fact, it considers the CPU interrupt) and
2) we know in advance which peripheral interrupts will be attached
to which CPU interrupt and, then, we can set them directly.
This prevents us from getting stuck while polling the different
network structures in `devif_poll_connections`. This is useful for
Wi-Fi/Bluetooth coexistence, specifically.

using up_putc makes it similar to ESP32S2 and ESP32S3 and perfectly
fits for showprogress usage.
Whenever a SPI flash operation is going to take place, it's
necessary to disable both the instruction and data cache. In order
to avoid the other CPU (if SMP is enabled) to retrieve data from
the SPI flash, it needs to be paused until the current SPI flash
operation finishes. All the code that "pauses" the other CPU (in
fact, the CPU spins until `up_cpu_resume` is called) needs to run
from the instruction RAM.

ESP32 and ESP32-S3 should use the ROM-defined versions of the libc
in flat build and, when building the protected mode, in the kernel.
The ROM-defined version of the libc functions can't be used in the
userspace, however, because it isn't allowed to access the memory
region in flash directly from the userspace. That being said,
`LIBC_PREVENT_STRING_KERNEL` should be selected to avoid building
any implementation of the libc, being the ROM-defined versions
linked instead.
NuttX's software implemented version of the libc will be built in
the userspace. Also, the assembly-defined version of some of the
libc functions (`XTENSA_xxx`) may also be selected to be used in
the userspace.

the actual partition is initialized); and 3) enables reconnecting
using `wapi reconnect` command and connect the device automatically
on bringup if `CONFIG_NETUTILS_NETINIT` is selected.

in SMP, signal processing cannot be nested, we use xcp.sigdeliver to identify whether there is currently a signal being processed, but this state does not match the actual situation
One possible scenario is that signal processing has already been completed, but an interrupt occurs, resulting in xcp.sigdeliver not being correctly set to NULL,
At this point, a new signal arrives, which can only be placed in the queue and cannot be processed immediately
Our solution is that signal processing and signal complete status are set in the same critical section, which can ensure status synchronization

The Inter-Processor Interrupt that pauses the other CPU generates
a level-1 interrupt which sets the PS.EXCM. This level-1 interrupt
is treated as an Exception and the bit PS.EXCM bit is automatically
reset on return from Exception. However, this is not the case here
because we are changing the execution to the signal trampoline.
Restoring the PS register with the PS.EXCM bit set would cause any
other exception to deviate execution to the DEC (double exception
vector), avoiding it to be treated correctly. According to the
xtensa ISA: "The process of taking an interrupt does not clear
the interrupt request. The process does set PS.EXCM to 1, which
disables level-1 interrupts in the interrupt handler. Typically,
the PS.EXCM is reset to 0 by the handler, after it has set up the
stack frame and masked the interrupt." Clean the saved PS.EXCM to
1) avoid an exception from being properly treated and 2) avoid
interrupts to be masked while delivering the signal.
