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.

This patch adds additional information to breadxavr board for AVR DA family
development. The text now covers how to use Button input driver and also
adds some information about using the hardware.

Unlike the Hello, world example, the NSH configuration can serve
as a starting point for testing other examples.

Introduced a template for board support documentation to help
standardize the documentation requirements for NuttX. Also added a small
section to the documentation contributing guidelines where templates can
be listed. This is part of item 9 in issue #16278 to improve NuttX
quality.

Installation instructions, license exceptions and supported features
of the RP2040 common among all boards have been moved exclusively to the
rp2040/index.rst file. Board documentation links back to the primary
source for installation instructions.

Previous implementation was not compatible with GlobalPlatform
API in the following ways:
- Registered mem IDs would begin from negatives when it should
have been greater than or equal to 0
- Register IOCTL would return 0 on success, when it should have
been returning a file descriptor.
- Register IOCTL would expect the user-space client to specify
TEE_SHM_* flags dictating its behaviour when in fact, libteec
never specifies flags.
This commit fixes all those issues. It uses nuttx/idr.h instead
of a linked list, and it uses `file_allocate` to provide file
descriptors for registered shared memory. Upon close(fd), the
memory is de-registered and freed accordingly. It also updates
the documentation accordingly.

The guide:
- explains the different OP-TEE transports available
in NuttX
- gives brief instructions on how to enable the OP-TEE
driver
- documents the IOCTLs supported, and
- shows typical usage in a NuttX app

This patch adds definitions for listed chips. No other changes are needed
as the chips are similar to the previously supported AVR128DA28 and all
that is needed is some definitions for extra peripherals.
AVR DA/DB family chips have single interrupt vector for all changes
on an I/O port. This poses problem when multiple drivers want to claim
the same interrupt (might happen for example with button and discrete
joystick drivers using pins on the same port.)
The I/O multiplexer solves it by providing interface similar
to irq_attach. However, it allows registration of multiple handlers
for the same interrupt vector with additional information recording
which pins should be serviced by each handler.
Only handler for pins that triggered the interrupt is then called.
Initial support adds chip specific files like Kconfig, flags for the compiler,
and basic functionality like system timer. Some files are stubs derived
from corresponding ATmega files but without the functionality they are
supposed to add (to be done in later patches)
Part of the work is altered copies of corresponding files for ATMega MCUs.
Initially supported is AVR128DA28.
