By integrating the Espressif`s HAL repository into the current
ESP32-S2 implementation on NuttX, it is possible to call functions
that makes it easier to setup the registers of the ESP32-S2,
enabling the usage of common Espressif drivers.
By integrating the Espressif`s HAL repository into the current
ESP32-S3 implementation on NuttX, it is possible to call functions
that make it easier to set up the registers of the ESP32-S3 and
enables the usage of common Espressif drivers. Please note that
Espressif's HAL repository was already being used for the Wi-Fi
driver. Then, this commit includes other source files to be used
by other drivers other than Wi-Fi and reorganize the build process.
This lower-half WS2812 LED driver uses the RMT peripheral of the
Espressif's SoCs to drive the RGB addressable LEDs. Compared to
the SPI-based implementation, it is faster!
The lower-half implementation of the RMT character driver based on
Espressif HAL enables using the RMT peripheral of ESP32, ESP32-S2
and ESP32-S3 as a common xtensa-based Espressif driver.
The RMT packages on Espressif SoCs are 4-byte long and are known as
"items". Please check the Techinal Reference Manual of the chip to
obtain more details.
1. Solve wifi may not work bug for bbpll not lock or not stable when enable RF.
2. Improved timing tuning stability on ESP32-S3.
The root cause of the issue:
The application won't re-calibrate the BBPLL clock if it's already enabled.
We add a force-recalib function in the app startup code to make sure even if
the patch is applied by OTA, the clock is still re-calibrated.

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`

Add registration function instrumentation API,
which can achieve instrumentation of entering and
exiting functions through the compiler's functionality.
We can use CONFIG_ARCH_INSTRUMENT_ALL to add instrumentation for all
source, or add '-finstrument-functions' to CFLAGS for Part of the
source.
Notice:
1. use CONFIG_ARCH_INSTRUMENT_ALL must mark _start or entry noinstrument_function,
becuase bss not set.
2. Make sure your callbacks are not instrumented recursively.
use instrument_register to register entry function and exit function.
They will be called by the instrumented function

1. If CONFIG_ESP32S3_PHY_INIT_DATA_IN_PARTITION and CONFIG_ESP32S3_SUPPORT_MULTIPLE_PHY_INIT_DATA are enabled,
PHY initialization data (PHY initialization data is used for RF calibration) will be loaded from a partition.
2. The corresponding PHY init data type can be automatically switched according to the country code,
China's PHY init data bin is used by default, country code can be modified through the wapi command: wapi country <ifname> <country code>.

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.
