net: phy: Set the driver when registering an MDIO bus device
mdiobus_register() registers a device which is already bound to a driver. Hence, the driver pointer should be set properly in order to track down the driver associated to the MDIO bus. This will be used to allow ethernet driver to pin down a MDIO bus driver, preventing it from being unloaded while the PHY device is running.
