net: phy: at803x: support qca8081 genphy_c45_pma_read_abilities 



qca8081 PHY supports to use genphy_c45_pma_read_abilities for
getting the PHY features supported except for the autoneg ability

but autoneg ability exists in MDIO_STAT1 instead of MMD7.1, add it
manually after calling genphy_c45_pma_read_abilities.
