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.
About libcxx with CONFIG_LIBC_ARCH_ATOMIC, it still
does not work. It is also needed to call nx_atomic_ ver
instead of __atomic ver in
libcxx/include/__atomic/cxx_atomic_lmpl.h.

This performs the DDR training for imx93-evk. In addition to the source code,
it downloads binaries which are included in the final image. The bootloader
must be ARCH_CORTEX_A53 instead of A55 due to atomic instructions that don't
work with the OCRAM / EL3 combination.

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.

Add lvgl and fb examples for qemu-intel64.
NOTE: multiboot framebufer doesn't work with -kernel argument in QEMU,
NuttX image must be loaded with -cdrom argument.
QEMU command to run examples:
qemu-system-x86_64 -m 2G -cpu host -enable-kvm -cdrom disk.iso -serial mon:stdio

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.
the link_library of the static target will cause PRIVATE to be inherited to nuttx,
resulting in duplicate linking and definition problems.
because all target static libraries will eventually be linked, there is no need to specify it explicitly.

Interrupts have to be disabled if interrupt worker processes them,
otherwise assertion may occur as another interrupt tries to queue
worker that is not available (because it processes previous interrupts).
Interrupts are re-enabled after the worker leaves the loop processing
previous interrupts.

This patch fix _eronly value which is used during boot process to initialize
.data section to sram.
Since .data section is 4 byte aligned in flash, also _eronly must follow this
alignment to stay coherent with the start address of .data.
If one of the sections preceeding .data has a size which is not 4 byte aligned,
the _eronly value does not match with .data physical address resulting in wrong
copy of data section to sram and thus an almost immediate hardfault.

In https://github.com/apache/nuttx/pull/13044,
LIBC_ARCH_ATOMIC was finally removed.
Howerver, the following chips still have the config.
- ARCH_CHIP_ESP32S3
- ARCH_CHIP_ESP32C3_GENERIC
- ARCH_CHIP_ESP32H2
This commit fixes the issue.
