net: davinci_emac: match the mdio device against its compatible if possible
[ Upstream commit ea0820bb771175c7d4192fc6f5b5c56b3c6d5239 ]
Device tree based systems without of_dev_auxdata will have the mdio
device named differently than "davinci_mdio(.0)". In this case use the
device's parent's compatible string for matching
