net: phylink: Add a mapping between MAC_CAPS and LINK_CAPS

Browse Source 
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.
