Currently many MAC drivers control the regulator supplying the PHY but
this is conceptually wrong. The regulator should be defined as a property
of the PHY node on the MDIO bus and controlled by the MDIO sub-system.

Add support for an optional PHY regulator which will be enabled before
optional deasserting of the reset signal.
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?
