This commit adds a max_pins field into the private struct.
AFEC0 has 11, AFEC1 has 12. The 12th pin of AFEC0 is an internal
pin connected to a temperature sensor, which we don't use.

Added I2C driver for the STM32H5. This driver uses the STM32H7 I2C driver as a base. The primary difference is setclock dynamically sets the I2C TIMINGR register instead of using hardcoded values. This allows the I2C peripherals to use any of the input clocks and set to any speed 0-1MHz. Additionally, Kconfig options were made available to set the Digital Noise Filter (DNF), Analog Noise Filter, I2C Clock source (i2c_ker_ck), as well as set i2c rise/fall times which are crucial to timing. Care must be taken when setting the clock source and filters, as not all settings are compatible with all i2c clock frequencies.
Some armv7-m-based SoCs do not work with atomic instructions,
even though armv7-m supports them.
To avoid using atomic instructions generated by gcc,
CONFIG_LIBC_ARCH_ATOMIC is newly introduced with which
arch_atomic.c is linked explicitly.
However, the function names need to be changed to avoid
build errors, since the functions described in stdatomic.h
are gcc built-in and inlined when the code is compiled.

when we build mbedtls in vela with ghs compiler, the mbedtls need to
access __ARM_ARCH and __ARM_FEATURE_DSP, and to construct the inline asm
code based on these two macros.
With ghs compiler, these two macros are not defined, and will be
evaluated as 0 by default, and thus will using to wrong inline asm code,
in order to handle this issue, we need to add conversion between the ghs
and gcc with __ARM_ARCH, __ARM_FEATURE_DSP

This commit adds files in preperation of adding ethernet drivers for the STM32H563 and Nucleo-H563ZI board.
It also modifies the pinmap to include ethernet pins (and cleaned up leftover comments from L5 file), as well as
add those pins to the board.h for the nucleo-h563zi.
Files added:
- arch/arm/src/stm32h5/hardware/stm32_ethernet.h
- arch/arm/src/stm32h5/hardware/stm32_sbs.h
- Not fully implemented, just register necessary for ethernet driver.
The naming scheme in board.h changed from STM32H5_ to STM32_. As a result we needed to adjust the naming of the STM32H5_BOARD_USExxx variables in stm32h5xx_rcc.c. Also made changes to allow the enabling of all 3 of HSI, CSI, or HSE in stm32_stdclockconfig. Lastly, the HSIDIV bits in RCC_CR were not being cleared before being set. Added logic to clear these bits.

This is a combination of 2 commits:
H5 Kconfig ethernet options added.
- This commit cleans up unecessary comments in the Kconfig and adds the the Ethernet/MAC menu.
The menu is copied from the H7 menu, since the peripheral IP is identical.
Remove trailing whitespaces.
Update suggested mask
PLL1FRACN was being set improperly. stm32h5xxx_rcc.c does not shift the value provided by board.h. So it was being set wrong. The defintions in stm32h5xxx_rcc.h shift the FRACN value and are now used by board.h. Also, board.h was not setting PLL1P properly. PLL1P can not have odd divisors. Therefore a value of 0 was invalid. Set it to a value of 1 (divide by 2), then adjust PLL1N to 31 and PLL1FRAC1 to 2048 to actually set SYSCLK to 250MHz.
Made fixes to issues from CI. Nxstyle and defconfig syntax.

currently, nuttx implements readv/writev on the top of read/write.
while it might work for the simplest cases, it's broken by design.
for example, it's impossible to make it work correctly for files
which need to preserve data boundaries without allocating a single
contiguous buffer. (udp socket, some character devices, etc)
this change is a start of the migration to a better design.
that is, implement read/write on the top of readv/writev.
to avoid a single huge change, following things will NOT be done in
this commit:
* fix actual bugs caused by the original readv-based-on-read design.
(cf. https://github.com/apache/nuttx/pull/12674)
* adapt filesystems/drivers to actually benefit from the new interface.
(except a few trivial examples)
* eventually retire the old interface.
* retire read/write syscalls. implement them in libc instead.
* pread/pwrite/preadv/pwritev (except the introduction of struct uio,
which is a preparation to back these variations with the new
interface.)

User may set CONFIG_MM_REGIONS=1 on purpose to disable CCM.
This is a completely normal system config and should not be treated as error.
I found this problem trying to run Renode with stm32f4discovery/nsh but
Renode doesn't support CCM so we have to disable it
If the core id needs to be included in the hardware register
calculation, up_cpu_index() should be used instead of this_cpu().

1. Enable timer and irq finally to make sure timer callback was already
registered. When the CPU resets, the values of some generic timer
registers are undefined. Enabling the timer interrupt in advance may
cause the timer to trigger early while the timer callback is not yet
registered. This results in the timer ISR being executed, which masks
the timer interrupt. Since the timer callback is not registered at
this point, the timer interrupt is not unmasked, further causing the
system scheduler to hang.
2. Remove timer mask for one-shot timer and that's in isr,
irq/fiq is disabled. Masking generic timer is not necessary, and it
may introduce risks, otherwise, mask/unmask must be pair in all
situations.
