drm/amdgpu: update xgmi info and vram_base_offset on resume
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.
