Will Aitken cd353ecafd drm/amdgpu: Use just sriov capability bit for xgmi ext peer link support
The legacy xgmi ta without EXTEND_PEER_LINKS support in sriov still
reports it as enabled. It then fails when the command is called. Rely on
the host capability bit instead.

v2: Replace other instances of supports_ext_link_info with this method.
Including sysfs emission for xgmi_port_num. Now amd-smi xgmi --metric
will output N/A for all cells when port_nums cannot be mapped in sriov
