From: Rafał Miłecki <rafal at milecki.pl>
Northstar devices have MDIO bus that may contain various PHYs attached.
A common example is USB 3.0 PHY (that doesn't have an MDIO driver yet).
Signed-off-by: Rafał Miłecki <rafal at milecki.pl>

V2: Disable MDIO bus by default.
Add mdio label to allow enabling it easily per board
