AMD GPU not functional on Focal with HWE kernel.
[ Test Case ]
See original description below.
[ Fix ]
Cherry-pick relevant commit from upstream linux-firmware.
[ Where Problems Could Occur ]
Broken graphics with AMD GPUs.
[ Original Description ]
Release: up-to-date Focal LTS (20.04.3)
Package-version: linux-firmware 1.187.20
Hardware model: [AMD/ATI] Chelsea LP [Radeon HD 7730M]
With the latest kernel upgrade (5.4 --> 5.11, if I recall correctly),
my laptop's discrete graphics stopped working. Looking at the logs, I
found these messages:
-- snippet --

In fact, file '/lib/firmware/amdgpu/verde_uvd.bin' was missing.
Running '$ dpkg -L linux-firmware | sort' gives this:

Copying the file from upstream
(https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-
firmware.git/tree/amdgpu/verde_uvd.bin) didn't work on my system,
probably because I use UEFI and the module wasn't signed (error
below):

I can confirm that reverting kernel driver to 'radeonsi' makes the
device usable again, but at the expense of Vulkan APIs (not supported
by this driver).
Could you, please, fix this?
