If MT7531_FORCE_EEE1G and MT7531_FORCE_EEE100 are unset, the abilities are left to be determined by PHY auto polling. The commit 40b5d2f15c09 ("net: dsa: mt7530: Add support for EEE features") made it so that the PMCR_FORCE_EEE1G and PMCR_FORCE_EEE100 bits are set on mt753x_phylink_mac_link_up(). But it did not set the MT7531_FORCE_EEE1G and MT7531_FORCE_EEE100 bits. Because of this, EEE will be enabled on the switch MACs by polling the PHY, regardless of the result of phy_init_eee(). Define these bits and add them to MT7531_FORCE_MODE which is being used by the subdriver. With this, EEE will be prevented from being enabled on the switch MACs when phy_init_eee() fails.
