phy: Add an mdio_device structure
Not all devices attached to an MDIO bus are phys. So add an mdio_device structure to represent the generic parts of an mdio device, and place this structure into the phy_device. Signed-off-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: David S. Miller <davem@davemloft.net>
