  vp9 hw decode broken on modern AMD apus, needs amdgpu update

Bug description:
  Current version of amdgpu binaries in linux-firmware shipped with
  ubuntu 22.04 (jammy) and ubuntu 23.10 (mantic) create various problems
  when decoding VP9 content with the iGPU on modern AMD mobile processor
  (rembrant and phoenix, i.e. 6xxxU/H, 7x40U/H and 7x35U/H processor).

  The issue has been reported and solved upstream:

  https://gitlab.freedesktop.org/mesa/mesa/-/issues/8044

  [EDIT: fixed link]

  Solution dates to the end of February: https://gitlab.com/kernel-
  firmware/linux-
  firmware/-/commit/977332782302476e1c863b09b840f463d0378807

  Ubuntu 24.04 already ships the updated binaries and should not be
  affected.

  Steps to reproduce:
  * on an affected system play a VP9 video with hardware decoding

  * https://www.phoronix.com/news/AMDGPU-Firmware-Fixes-VP9

  Workaround:
  * download the amdgpu folder from upstream linux-firmware repos
  * compress each file with zstd
  * copy into /lib/firmware/amdgpu
  * regenerate the initrd

  I'm currently running ubuntu 23.10 (mantic) with binaries from
  upstream and the issue is solved.
