Subject: [PATCH 1942/2940] drm/amd/powerplay: valid Vega10
DPMTABLE_OD_UPDATE_VDDC settings V2
With user specified voltage(DPMTABLE_OD_UPDATE_VDDC), the AVFS
will be disabled. However, the buggy code makes this actually not
working as expected.
- V2: clear all OD flags excpet DPMTABLE_OD_UPDATE_VDDC
