reason:
up_set_current_regs initially had two functions:
1: To mark the entry into an interrupt state.
2: To record the context before an interrupt/exception. If we switch to
a new task, we need to store the upcoming context regs by calling up_set_current_regs(regs).
Currently, we record the context in other ways, so the second function is obsolete.
Therefore, we need to rename up_set_current_regs to better reflect its actual meaning,
which is solely to mark an interrupt.

After compilation, when starting nsh, the following crash occurs.
==2500151==Shadow memory range interleaves with an existing memory mapping. ASan cannot proceed correctly. ABORTING.
==2500151==ASan shadow was supposed to be located in the [0x1ffff000-0x3fffffff] range.
==2500151==Process memory map follows:
0x30000000-0x33dd4000 /nuttx/nuttx
To avoid overlaps, change the starting address of the text segment.
Using Ttext-segment=0x30000000 causes a crash when starting the 32-bit SIM.
Using -Ttext-segment=0x50000000 causes a crash when starting the 64-bit SIM.
Setting -Ttext-segment=0x40000000 resolves all issues perfectly.

Adds ADC support with minimal feature set (no DMA or Timers etc). A new nucleo-h563zi configuration was added to
provide easy testing with the adc example NSH addon.

Split nucleo-f4x1re into nucleo-f401re and nucleo-f411re.
These are separate boards and should be in separate directories as it's
done for all other nucleo boards in NuttX
The PLL clock configuration was simplified on the assumption the clocks are correctly set in the board.h file. Instead of seperate conditions
for register components, assume the relevant PLL registers are fully defined in board.h. This should result in easier to understand defines in board.h
and simpler code flow in the standard clock configuration function.
Changes were mad in the board file alongside changing the arch files. Changes to board/stm32h5:
- PLL1 has been configured to use integer instead of fractional mode to reach the 250 MHz target. PLL2 and PLL3 configurations were
removed since they are currently unused in the H5 configuration.
- PLL1 output was verified by testing for changes in serial baud rate.
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.
