Narayan Reddy 48e0d60b07 nvethernet: PHY register read/write for fixed-link case ...

ethernet@<address> {
    nvidia,mdio_address = <PHY MDIO bus address>;

    fixed-link {
	speed = <1000>;
	full-duplex;
    };
};

1. Added nvidia DT property (nvidia,mdio_address) for passing
   the PHY MDIO bus address.
2. If this property present in DT then driver calls PHY MDIO
   read/write functions directly instead of going through PHY subsystem.
3. If this property is not present – then driver PHY mdio
   read/write goes through PHY subsystem.
