[PATCH 0/2] add correctable error query support on arcturus

[Guchun Chen]

Below two patches are submmited to promise UMC correctable error query
working fine on arcturus.
Patch 1 is to switch RSMU UMC index access to SMN interface to make it
stable, and to be consistent with other register access in this file.
Patch 2 is to decouple EccErrCnt error count query and clear operation,
due to unknown hardware cause.

Both are verified on arcturus and Vega20.

Guchun Chen (2):
  drm/amdgpu: switch to SMN interface to operate RSMU index mode
  drm/amdgpu: decouple EccErrCnt query and clear operation.
