Pull request efi-2026-01-rc2

CI: https://source.denx.de/u-boot/custodians/u-boot-efi/-/pipelines/28208

Documentation:

* bootstd: Describe environment variable extension_overlay_addr
  environment and remove extension support from TODO list

EFI:

* Correct the detection of the video mode in the EFI payload app:
  - Use struct efi_gop_mode_info in the definition of struct
    efi_entry_gopmode.
  - In function get_mode_from_entry() use the correct type for the video
    mode structure.
* Use a valid error code as return value in efi_store_memory_map().
* Avoid a memory leak for the variable name in efi_bl_create_block_device().
* Correct the code indentation in efi_uc_stop().
* Correct the description of struct efi_priv.
* Fix typos in code comments.

Other:

* qfw: Add more fields and a heading to qfw list
* Fix the support for ACPI pass-through on ARM and RISC-V:
  Avoid zeroing out the XSDT address
* test: provide unit test for 'acpi list' command
