This PR includes some fixes to the falcon mode documentation to prepare for the 12.00 release, notably the following:

  1. Remove references to ti-falcon yocto override, instead point users to upstream U-Boot docs
  2. Document the missing ti-u-boot patch for fixing R5 falcon mode
  3. Add AM62d to list of R5 falcon mode supported platforms
  4. Add build steps for AM62l's A53 SPL based falcon mode

Due to ongoing work in improving oe-core's fitImage creation in yocto,
the support for ti-falcon override for enabling falcon mode is dropped
in 12.00.

Therefore update the docs to point users to upstream U-Boot
documentation instead.

The patch ee3048ee0822 ("mach-k3: restrict SPL_LOAD_FIT_ADDRESS to A53
falcon mode") in ti-u-boot was missed from the 12.0 release but is
required for enabling falcon mode.

Therefore this commit adds a temporary reference to the missing patch in
the documentation.

This patch documents falcon-mode for AM62d EVM, the upstream
documentation is on v2026.04 instead of v2026.01 unlike other platforms
since AM62d's docs were not updated upstream until v2026.04 release of
U-Boot.

Signed-off-by: Anshul Dalal <anshuld@ti.com>
Falcon mode support for AM62l can be enabled using the
am62lx_falcon.config U-Boot config fragment with no changes to the rest
of rootfs.

This patch documents the same in U-Boot's build process.
