A major regression was reported on commit 60dc78a7 ("amdgpu: update GC
11.0.1 firmware for amd.5.5 release") where Phoenix integrated GPUs
aren't able to boot up with `amdgpu` loaded.

This is fixed internal commit 8b27b052488cee45b453dcab6d034bb80a964e61.
To avoid another regression from a mismatch, pull in a whole snapshot
of all GC firmware at this commit instead of just the one file.
