Subject: drm/amdgpu: access register without KIQ
Git-commit: fa1d04e9a896c468f0882425f5ba452a4b424108
Patch-mainline: v4.19-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166
there is no need to access register such as mmSMC_IND_INDEX_11
and mmSMC_IND_DATA_11 through KIQ because they are VF-copy.
