Tiecheng Zhou df5e984c8b drm/amdgpu/sriov: workaround on rev_id for Navi12 under sriov ...

guest vm gets 0xffffffff when reading RCC_DEV0_EPF0_STRAP0,
as a consequence, the rev_id and external_rev_id are wrong.

workaround it by hardcoding the rev_id to 0, which is the default value.

v2. add comment in the code
