realtek: pcs: move polarity into SerDes struct

As a first real usage of the new SerDes struct, move the polarity
configuration there. It was previously located in the global rtpcs_ctrl
struct as an array, indexed by SerDes id. Because this is per-SerDes
information, the new SerDes struct is the correct place to live in.
