Public bug reported:

SRU Justification

Impact: With 5.3 update-initramfs reports several missing amdgpu
firmware files:

update-initramfs: Generating /boot/initrd.img-5.3.0-19-generic
W: Possible missing firmware /lib/firmware/amdgpu/vega20_ta.bin for module 
amdgpu
W: Possible missing firmware /lib/firmware/amdgpu/raven_kicker_rlc.bin for 
module amdgpu
W: Possible missing firmware /lib/firmware/amdgpu/navi10_mes.bin for module 
amdgpu

Of these, only raven_kicker_rlc.bin has been added to upstream linux-
firmware.

Fix: Add raven_kicker_rlc.bin to linux firmware, and remove the other
files from modinfo for amdgpu.

Test Case: Once fixed, the warnings from update-initramfs should be
gone.

Regression Potential: Adding a missing firmware is unlikely to break any
working hardware. Removing the other missing files from modinfo will not
cause regressions either, however if the firmware is added later update-
initramfs will not add the files to the initramfs until the firmware is
added back to modinfo.
