drm/amdgpu/gmc8: SRIOV need to program fb location
SRIOV won't do vbios post in guest OS, and the mmMC_VM_FB_LOCATION
is pf and vf copy, so still need to program fb location for SRIOV.
v2: No need to stop mc, and update gmc_v8_0_vram_gtt_location as well.
v3: New line after the stack variables
BUG: SWDEV-126629
