Adds a platform specific implementation for tickless schedular operation. This includes:
- Tickless operation for vexriscv cores.
- Tickless operation for vexriscv-smp cores.
- Ticked operation for vexriscv-smp cores.
Ticked operation for vexriscv core has been refactored.
Additional default configuration added to demonstrate operation.
Both tickless and ticked options use Litex timer0 for scheduling intervals. This is significantly faster than interfaceing with the risc-v mtimer through opensbi.
Example of /proc/PID/group/fd in this case:
FD OFLAGS TYPE POS PATH
17 67 9 0 socket:[domain 16, type 2, proto 0]

Considering kernel code, it's reasonable to use `PANIC()` instead
of `assert(0)` to handle with situations that require abort. Unlike
`assert`, `PANIC()` doesn't dependent on `NDEBUG`.
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.
- Fix macro values from `arch/xtensa/include/esp32s3/irq.h`
- Remove references to unexisting edge-triggered CPU interrupts
- Add `esp32s3_getirq` to get IRQ based on core and the `cpuint`
RTC subsystem controls not only the RTC itself but functions that
use RTC-enabled features like Bluetooth and Wi-Fi. Initialization
must be performed during the system start-up.
Verification:
Write a packet, the length is bigger than CONFIG_DEV_FIFO_SIZE.
The return value should be -1, and the errno is EMSGSIZE.
