Commit Message

Russell King (Oracle) March 14, 2020, 10:15 a.m. UTC 
The port_link_state method is only used by mv88e6xxx_port_setup_mac(),
which is now only called during port setup, rather than also being
called via phylink's mac_config method.

Remove this now unnecessary optimisation, which allows us to remove the
port_link_state methods as well.
