mdio_bus: Generalise of_mdiobus_link_phydev()
This function should work with any sort of MDIO device which can be probed on the bus, not just PHY devices. So generalise it. 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>
