dt-bindings: net: macb: Add mdio bus child node
This adds an optional mdio bus child node. If present, the mac will look for PHYs there instead of directly under the top-level node. This eliminates any ambiguity about whether child nodes are PHYs, and allows the MDIO bus to contain non-PHY devices.
