drm/amdgpu: update xgmi info and vram_base_offset on resume

Browse Source 
For SRIOV VM env with XGMI enabled systems, XGMI physical node id may
change when hibernate and resume with different VF.

Update XGMI info and vram_base_offset on resume for gfx444 SRIOV env.
Add amdgpu_virt_xgmi_migrate_enabled() as the feature flag.
