The binding docs requires for SMI-connected devices that the switch
must have a child node named "mdio" and with a compatible string of
"realtek,smi-mdio". Meanwile, for MDIO-connected switches, the binding
docs only requires a child node named "mdio".

This patch changes the driver to use the common denominator for both
interfaces, looking for the MDIO node by name, ignoring the compatible
string.
