The current default number of IRQ state lists for PHY initialization is 3 (i.e. NR_IRQSTATE_FLAGS).
When calling in a nested manner, the number of times the concurrent behavior enters the critical section exceeds 3, which will trigger an assert crash.
Therefore, the size of NR_IRQSTATE_FLAGS needs to be increased, this PR makes NR_IRQSTATE_FLAGS configurable.

examples:
There are two threads involved: thread A with a priority of 100 and
thread B with a priority of 101. Here's how they interact:
When thread A releases a semaphore, thread B is scheduled to execute
some code and may reacquire the semaphore. If no other tasks are ready,
thread A will be scheduled to run.
This continuous process can lead to a busy loop.
Thread A: Thread B:
while (nxsem_get_value(&priv->wait, &semcount) >= 0 && <---
semcount <= 0) | 2)context switch
{ 1)contex switch |
nxsem_post(&priv->wait); -------------> run some code and nxsem_wait again

(the ipv6 address has a direct relation with the node address)
Introduce the option to add a 4 byte random number to the mac header
as a preparation for ciphered data exchange.

Fix cooling state not decreasing error when the temperature is kept at low trip(stable, not dropping).
Test on "sim:thermal", log is from /proc/thermal/cpu-thermal and see thermal/thermal_dummy.c for trip point details.
e.g. The temperature decreasing from 71 to 65 and then kept.
z:cpu-thermal t:71 t:1 h:16 l:0 c:fan0 s:16|16
a. Without this patch, the cooling state of "fan0" will be kept at 15, even if the temperature is at a lower trip:
z:cpu-thermal t:65 t:1 h:16 l:0 c:fan0 s:15|15
... ...
z:cpu-thermal t:65 t:1 h:16 l:0 c:fan0 s:15|15
b. With this patch, the cooling state of "fan0" was continually decreasing to zero according to current trip point:
z:cpu-thermal t:65 t:1 h:16 l:0 c:fan0 s:15|15
... ...
z:cpu-thermal t:65 t:1 h:16 l:0 c:fan0 s:0|0

In a recent patch the socketcan timestamp generation was moved
to add it also when there is an active reader (previously the timestamp
was only added before storing the CAN frame in the read-ahead list).
It was working fine but I realized that the can_callback function is
also called when sending frames. In this case, the IO block is not allocated
yet and the code breaks.
This PR is to only generate the timestamp if the IO block is not NULL
(reading path) and skip it when it is NULL (sending path)

The kernel mapping should be performed in sem_wait (thread level) as
virtual memory mappings cannot be added from interrupt, at least for now.
The reason?
kmm_map() depends on mm_map_add(), which in turn uses a mutex for mutual
exclusion. Using mutexes from interrupt level is not permitted.
Mapping tcb->waitobj into kernel virtual memory directly in sem_wait()
makes sense, since accessing tcb->waitobj via a user virtual address can
lead to unexpected results (the wrong mappings can be in place).
Add the mtimer _tick operations for use when tickless mode is not used.
This corrects the tick-based timing calculations, removing tick timer drift
and rounding errors causing early wdog expirations.

I found that the gpio example code can't be tested on nrf5340-dk.
Enabling CONFIG_DEV_GPIO wouldn't register gpio pins as /dev/gpio*.
NRF5340-dk has 4 LEDs and 4 User Buttons.
By setting CONFIG_DEV_GPIO=y,
- 4 LEDs will be configured as GPIO outputs
- 2 Buttons as GPIO inputs, and
- 2 Buttons as GPIO interrupt inputs
This PR will allows user to test GPIO examples on NRF5340-dk board.

Add support for the STM32H5 ICACHE peripheral. The CortexM33 does not have typical embedded icache and dcache. Instead STM32H5 provides the ICACHE as a separate peripheral that needs to be configured. This commit adds the stm32h5 specific icache driver. This driver named functions like those in <nuttx/cache.h>. However since the CortexM33 does not have cache itself, ARCH_ICACHE is not enabled. Therefore these stm32h5 specific functions were developed.
