Bug description:
  [ Impact ]

  I noticed on a system running linux-firmware
  20240318.git3b128b60-0ubuntu2.14 amdtee is working properly:

  ------------
  $ dpkg -l | grep linux-firmware

  ii  linux-firmware
  20240318.git3b128b60-0ubuntu2.14         amd64        Firmware for
  Linux kernel drivers

  $ dpkg -L linux-firmware| grep tee

  /lib/firmware/amdtee
  /lib/firmware/amdtee/773bd96f-b83f-4d52-b12dc529b13d8543.bin.zst
  /lib/firmware/amdtee/amd_pmf_v3.bin.zst
  ------------

  However since upgrading past that the amdtee firmware has disappeared.
  This breaks amd-pmf.

  ------------
  $ dpkg -l | grep linux-firmware
  ii  linux-firmware                                20240318.git3b128b60-0ubuntu2.19         amd64        Firmware for Linux kernel drivers

  $ dpkg -L linux-firmware | grep tee
  $
  ------------

  Looking for related bugs I found
  https://bugs.launchpad.net/ubuntu/+source/amd64-microcode/+bug/2112488.

  So I looked and I don't see anything in amd64-microcode either.

  ------------
  $ dpkg -l | grep amd64-microcode
  ii  amd64-microcode                               3.20250311.1ubuntu0.24.04.1              amd64        Processor microcode firmware for AMD CPUs
  $ dpkg -L amd64-microcode | grep tee
  $
  ------------

  So I guess this has regressed since 20240318.git3b128b60-0ubuntu2.15.
