The enabling/disabling of EEE in the MAC should happen as a result of auto negotiation. So move the enable/disable into lan743x_phy_link_status_change() which gets called by phylib when there is a change in link status. lan743x_ethtool_set_eee() now just programs the hardware with the LTI timer value, and passed everything else to phylib, so it can correctly setup the PHY. lan743x_ethtool_get_eee() relies on phylib doing most of the work, the MAC driver just adds the LTI timer value.
