[U-Boot] [U-boot] [Patch v2 4/5] net: keystone_net: register eth PHYs on MDIO bus

[Ivan Khoronzhuk]

As MDIO bus has been added we can register PHYs on it.
Register only for SGMII ports connected with appropriate PHY.
After registration, the PHY driver will be probed according to the
hardware on board.
