phylink allows MAC drivers to report the capabilities in terms of speed, duplex and pause support. This is done through a dedicated set of enum values in the form of the MAC_ capabilities. They are very close to what the LINK_CAPA_xxx can express, with the difference that LINK_CAPA don't have any information about Pause/Asym Pause support. To prepare converting phylink to using the phy_caps, add the mapping between MAC capabilities and phy_caps. While doing so, we move the phylink_caps_params array up a bit to simplify future commits.
