Lijo Lazar 33e8da29bc drm/amdgpu: Remove ATC L2 access for MMHUB 2.1.x
commit d2c4c1569a upstream.

MMHUB 2.1.x versions don't have ATCL2. Remove accesses to ATCL2 registers.

Since they are non-existing registers, read access will cause a
'Completer Abort' and gets reported when AER is enabled with the below patch.
Tagging with the patch so that this is backported along with it.

v2: squash in uninitialized warning fix (Nathan Chancellor)

Fixes: 8795e182b0 ("PCI/portdrv: Don't disable AER reporting in get_port_device_capability()")
