Please don't. phylink_mac_change() is the older version from before
phylink ended up with split PCS support. Some drivers still use it
(because I haven't got around to sorting those out - I've got the
mess formerly known as stmmac that I'm dealing with.)

It only makes sense to tell phylink about a change in status if there
is a PCS, because that's the only way phylink can be told of updated
status.
