Bug description:
  [Impact]
  amd-pmf driver requires a new firmware which does not exists in noble yet.

  Aug 18 07:40:28 localhost kernel: tee tee0: Direct firmware load for /amdtee/f29bb3d9-bd66-5441-afb88acc2b2b60d6.bin failed with error -2

  Aug 18 07:40:28 localhost kernel: amd-pmf AMDI0107:00: registered PMF device successfully

  [Fix]
  The required firmware is from this commit
  86d528c2 amd_pmf: Update AMD PMF TA Firmware to v3.1

  [Test]
  Verify the dmesg after booted up, there should be no amd-pmf firmware not found errors

  [Where problems could occur]
  The device works after this SRU, so no regression.
