drm/amdgpu: Add new PF2VF flags for VF register access method
Add 3 sub flags to notify guest for indirect reg access of
gc, mmhub and ih
The host sets these flags depending on L1 RAP version,
asic and other scenarios. These flags ensure that
there is compatibility between different guest/host/vbios versions.
