I wonder if this is the right place for this - MDIO devices do not have
to be PHYs - they can be switches, and using "phy-supply" for a switch
doesn't seem logical.

However, I can see the utility of having having a supply provided for
all mdio devices, so it seems to me to be a naming issue.  Andrew?
