[PATCH RFC net-next 14/14] net: phylink: remove legacy mac_an_restart() method

["Russell King (Oracle)" <rmk+kernel@armlinux.org.uk>]

The mac_an_restart() method is now completely unused, and has been
superseded by phylink_pcs support. Remove this method.

Since phylink_pcs_mac_an_restart() now only deals with the PCS, rename
the function to remove the _mac infix.
