Harsimran Singh Tungal 1843e9e2eb arm-bsp: corstone1000: Enable FF-A-backed EFI runtime variables and selftests ...

This series wires up Arm FF-A support for EFI runtime services by
factoring runtime-safe helpers into the FF-A bus, layer the EFI
variable TEE transport on top, and then rehome the helper exports
so there’s a single implementation shared between boot and
runtime paths. Corstone1000 enables the self-test command and
expands the runtime variable selftest so it exercises non-volatile
storage across reboots.

Key Changes
===========
 - Add the FF-A runtime transport patch stack to the corstone1000
   U-Boot recipe.

 - Enable EFI runtime variable handling over FF-A and include the
   bootefi selftests and sandbox FF-A runtime transport test.

 - Increase the FIP partition sizes from 2MiB to 2.5MiB
   and update TFA_FIP_RE_SIGN_BIN_SIZE from 0x00200000 to 0x00280000
   to reflect the new allocation. The size of u-boot-EFI-2025.10-r0.bin
   has increased from ~707KB to ~944KB following the FF-A/EFI runtime
   related changes. As this binary is packaged within the FIP, the
   overall signed FIP size has grown accordingly.

 - Add a Yocto patch to increase the FIP partition size from
   2MB to 2.5MB in the TF-M flash layout for Corstone-1000.
