eliminate code duplication and improve maintainability.

Add a new function nxsched_wakeup() to the scheduler,
which allows waking up a sleeping task before its timeout.

Currently, there is duplicated code in nxsig_wait_irq() and nxsig_timeout().
This patch updates the input parameters of nxsig_wait_irq() so that it can
be reused in nxsig_timeout(), reducing code duplication and improving
maintainability.

nxsig_wait_irq() is always invoked within an existing critical section,
and the task state is already verified, similar to nxsem_wait_irq().
Therefore, the additional critical section protection and task state
check inside the function are redundant and have been removed.

This is the case for USB2517 USB HUB. Also improved the driver to
avoid mistakes: initially I changed g_id[3], but the in register
there is another field where we need to pass this size again. So
it is better to use ARRAY_SIZE() macro to avoid mistakes.

This function can identify (during the runtime) whether the chip
is revB or revA. Bear in mind PIC32CZ2051CA70 is always revB.
Allows to have one binary compatible with SAMV7 and PIC32.
Thanks to Pavel Pisa and Michal Lenc for the suggested code.

Previously the function "up_cpu_pause" was used for preventing all other
CPUs from executing code from flash.
The above function was removed in d8cb7759.
Now flash operations work on rp2040 in SMP mode by blocking all but the
current CPU for the duration of the critical function (write or erase).
Closes: #16203

Adding the stm32h5 pwm driver. This is almost an exact copy of the stm32h7 pwm driver. I confirmed the timers for the h5 are version v2 and added the preprocessor definition. This commit was tested on a stm32h5 nucleo-h563zi development board. Necessary board files and a pwm config have been added. Added pin mappings for all timer outputs.

Added documentation regarding nucleo-h563zi:pwm config.
Removed CONFIG_STM32H5_PWM guard at the top. Fixed IRQs for tim1 and tim8. Added H5 to list of Timer IP v2 timers.
Conditionally compile stm32_serial.c.
Add stm32_pwm.c to CMakeLists.txt
Curently, the driver code for HW accelerated AES is not usable

it as well as a few bugs.

Fix exception issue when PM and DEBUG_ASSERTIONS enabled for esp32 and esp32s3.
This error happens due to PM system workflow, when system gets into sleep-modes with
removing PM_NORMAL count, system is raising an exception for not having
enough number of PM_NORMAL state count if DEBUG_ASSERTIONS enabled.

- CMake added board Raspberry Pi Pico 2 RISC-V
- Created a file rp23xx_common_pico.h with function
prototype
int rp23xx_dev_gpio_init(void);
to allow cmake + ninja to build without errors.

If the compiler optimization is disabled, the stack-usage of inlining functions will not be optimized.
In this case, force inlining can lead to stack-overflow (e.g.
qemu-armeabi-v7a-bl). This commit replaced the definition of the
always_inline_function and inline_function with the inline
keyword to avoid force-inlining.

This commit implemented optimized runtime-invariant integer division
proposed by T. Granlund and L. Montgomery. It can be used to convert the
hardware clock cycles to seconds, where the clock frequency is runtime-invariant.

When closing a serial port an ongoing TX DMA transfer will be stopped. This can cause
one (or multiple) the following:
- dev->dmatx.length != 0
- dev->dmatx.nlength != 0
- stm32_dmaresidual returning a non-zero residual
This is caused by length/nlength not being set to 0 at startup or during closing.
In addition the DMA_SxNDTR register is not set to 0 at startup or during closing.
This commit solves the issue by setting the variables and register to 0 during closing.

The nxsched_switch_context() function should only be called
when a task switch actually occurs. The RISC-V architecture
already performs this call in riscv_perform_syscall(),
so this PR removed the redundant nxsched_switch_context() call in
up_switch_context().
