mdio: Add support for mdio drivers.
Not all devices on an MDIO bus are PHYs. Meaning not all MDIO drivers are PHY drivers. Add support for generic MDIO drivers. Signed-off-by: Andrew Lunn <andrew@lunn.ch> Reviewed-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
