realtek: pcs: add per-link port storage to rtpcs_serdes

Browse Source 
Add an s16 link_port[] array to struct rtpcs_serdes, initialised to
-1 in probe. This is preparatory storage for the port number that
each link serves; it will be populated in the follow-up fwnode_pcs
migration commit by scanning consumer DT nodes for their reg, and
consumed by the resolver when allocating rtpcs_link.
