drm/amdgpu: xgmi_fill_topology_info
1. Use the mirrored topology info to fill links for VF.
The new solution is required to simplify and optimize host driver logic.
Only use the new solution for VFs that support full duplex and
extended_peer_link_info otherwise the info would be incomplete.
2. avoid calling extended_link_info on VF as its not supported
