net: dsa: mv88e6xxx: extend phylink to Serdes PHYs
Extend the mv88e6xxx phylink implementation down to Serdes PHYs, which handle the PCS layer of such links. - Implement phylink PCS link state reading, so that we can provide ethtool with the linkmodes and link speed in the expected manner. Note: this will only be called for in-band negotiation, which is only supported by the serdes interfaces. - Implement phylink PCS configuration, so that the in-band AN and advertisement can be configured. - Implement phylink PCS negotiation restart, so that the in-band AN can be restarted. - Implement phylink PCS link up, so that when operating out-of-band, the Serdes can be configured for the appropriate fixed speed mode.
