41       Fman has internal MDIO for internal PCS(Physical
42       Coding Sublayer) PHYs and external MDIO for external PHYs.
44       MDIO are different. Must be included for internal MDIO.

59       set when reading internal PCS registers. MDIO reads to
64       PCS registers through MDIO. As a workaround, all internal
65       MDIO accesses should ignore the MDIO_CFG[MDIO_RD_ER] bit.
67       For internal PHY device on internal mdio bus, a PHY node should be created.

70       - For "fsl,fman-mdio" compatible internal mdio bus, the PHY is TBI PHY.
71       - For "fsl,fman-memac-mdio" compatible internal mdio bus, the PHY is PCS PHY.
