The Renesas Ethernet AVB bindings do not allow the MDIO bus to be
described. This has not been needed as only a single PHY is
supported and no MDIO bus properties have been needed.
Add an optional mdio node to the binding which allows the MDIO bus to be
described and allow bus properties to be set.

* Changes since v2
- Mark the PHY pattern as deprecated and add a comment that new bindings
should describe the PHY inside the MDIO node.
