Subject: [PATCH net-next 2/3] dpaa2-eth: add phylink_mac_ops stub callbacks

For the moment, we do not have a way to query the PCS link state
or to restart aneg on it. Add stub functions for both of the callbacks
since phylink can provoke an oops when an SFP module has been inserted.

Fixes: 719479230893 ("dpaa2-eth: add MAC/PHY support through phylink")
