net: phy: marvell-88q2xxx: cleanup mv88q2xxx_config_init

mv88q2xxx_config_init calls genphy_c45_read_pma which is done by
mv88q2xxx_read_status, it calls also mv88q2xxx_config_aneg which is
also called by the PHY state machine. Let the PHY state machine handle
the phydriver ops in their intendend way.
