Subject: drm/amdgpu: Disable FRU read on Arcturus
Git-commit: 69d0c18dda2dae4cfbf73d4ffaa5aff6dc69894a
Patch-mainline: v5.8-rc1
References: jsc#SLE-12680, jsc#SLE-12880, jsc#SLE-12882, jsc#SLE-12883, jsc#SLE-13496, jsc#SLE-15322
Update the list with supported Arcturus chips, but disable for now until
final list is confirmed.
Ideally we can poll atombios for FRU support, instead of maintaining
this list of chips, but this will enable serial number reading for
supported ASICs for the time-being.
