ARM: dts: sunxi: Add mdio bus sub-node to GMAC
The DWMAC binding never supported having the Ethernet PHY node as a direct child to the controller, nor did it support the "phy" property as a way to specify which Ethernet PHY to use. What seemed to work was simply the implementation ignoring the "phy" property and instead probing all addresses on the MDIO bus and using the first available one. The recent switch from "phy" to "phy-handle" breaks the assumptions of the implementation, and does not match what the binding requires. The binding requires that if an MDIO bus is described, it shall be a sub-node with the "snps,dwmac-mdio" compatible string. Add a device node for the MDIO bus, and move the Ethernet PHY node under it. Also fix up the #address-cells and #size-cells properties where needed.
