This commit adds support for MAX31855 and MAX6675 thermocouple
sensors on the STM32F401RC-RS485 board via SPI1. It also updates
the board documentation accordingly.

- Committing initial code for DTS. Missing ISR. Works for PCLK1. Cannot get to work for LSE.
- Pushing everything. Working with LSE now.
- Many fixes. Fixed interrupt setting. Added data structures.
- Changed interrupt handling. Removed FARs. Added Kconfig options for selecting interrupts.
- Updated info and formatting.
- Formatting fixes.
- Formatting.
- Changed iten to regval.
- Removed Triggger
- Formatting fixes per Pull request.
- Changed private_types to have stm32_ prefix. Used depends on for DTS Kconfig Menu. Fixed formatting per PR.
- Fixed spacing of function prototypes.
- Fixed indent on line
- Added documentation for STM32H5 and Nucleo-H563ZI regarding DTS. Also added GPDMA support to STM32H5 documentation (previous PR). Made stm32_dts.c more modular. stm32_dts_activate is now much more readable. Added comments/descriptions to private functions. Lastly, added a nucleo-h563zi:dts configuration.
This commit creates a sbutton device that uses a single button to
create a keyboard driver that returns TAB or ENTER depending how
long the user keeps the button pressed.

AVR uses Hardward architecture with separate address space for program
memory (flash) and data memory (RAM). Normal program flow can only
access data memory which means that all variables - including const
variables - have to be copied into RAM to be accessible. (This happens
automatically during startup.)
It is possible to work around this limitation in software but that
can have severe impact on performance and/or API complexity. It is hardly
feasible to change NuttX interfaces in a way that would allow to make use
of this workaround.
On newer AVR families, there is an alternative option enabled by this patch.
These chips map part of their program memory (a 32kB window) into data
memory address space. This patch leverages this feature and adds support
for placing const variables into the mapped window. No copy to RAM is done
for them.
Const variables are therefore loaded directly from flash (not consuming
RAM) while still being available to be used by any NuttX interface.
Linker script of breadxavr board is changed to make use of these changes.
Tested by verifying string addresses - parameters in printf call
in a custom application (and also by running the application and verifying
its output.)
Documentation tested by build.

This patch adds a document that describes why const variables need to be
copied into the RAM in AVR architecture for normal program flow in NuttX.
It then describes options of accessing them directly from the flash without
need to do any copying.
Patch was tested by building the documentation.

This commit adds SD card support to the WeAct STM32H743 board configuration.
The implementation enables the board to interface with SD cards through the
SDMMC peripheral, allowing file system operations and data storage capabilities.

This implements an interrupt-based SPI driver for the BCM2711 SPI
interfaces (excluding auxiliary SPI interfaces). Only tested on SPI0
since proprietary firmware does not initialize any other SPI interfaces,
and doing so will require reverse engineering.
The document context-switch-notes.rst was leaking into "Supported Platforms"
table of contents. To fix this, it was moved to separate common directory
and referenced from AVR index.rst
Similar to that, the gpio_intr_mux.rst document was leaking into list
of supported AVR families. This too was fixed by moving it to separate
docs directory.
The change was tested by building the Documentation using make html

After a mailing list suggestion, the indirection that enabled
ARCH_TOOLCHAIN_GCC only when user requested it is removed.
The indirection was a safety measure for chips and boards with linker
scripts that (possibly) do not handle keeping for example .vectors
section even if the linker considers it unreferenced.
Instead, all existing configurations now disable
CONFIG_DEBUG_OPT_UNUSED_SECTIONS to prevent the linker from removing
any code. (Preserving previous behaviour.) This can be removed again
at some point after making sure that corresponding linker script
only removes code that is truly unused.
