phylink_ethtool_get_eee() fills in eee_enabled, eee_active and
tx_lpi_enabled.  So there is no need for the MAC driver to do it as
well.

Complete patch set is tested on stmmac interface of Polyhex Debix Model A
i.MX8MPlus board.

The only thing that's changed from before is that we're not advertising
EEE as a default anymore.
