Unify the 2 existing PCS drivers (lynx and xpcs) by doing a similar thing on probe, which is to have a *_create function that takes a struct mdio_device * given by the caller, and builds a private PCS structure around that. This changes stmmac to hold only a pointer to the xpcs, as opposed to the full structure. This will be used in the next patch when struct mdio_xpcs_ops is removed. Currently a pointer to struct mdio_xpcs_ops is used as a shorthand to determine whether the port has an XPCS or not. We can do the same now with the mdio_xpcs_args pointer.
