When STMMAC is paired with Energy-Efficient Ethernet(EEE) capable PHY, and the PHY is advertising EEE by default, we need to enable EEE on the xPCS side too, instead of having user to manually trigger the enabling config via ethtool. Fixed this by adding xpcs_config_eee() call in stmmac_eee_init().
