net: add support for MDIO devices
On the MDIO bus we can have PHYs and some other type of devices.
Typical not_PHY MDIO devices do not have easy detectable ID and can't be
used as-is by the PHY framework. So, add additional handler to register
MDIO devices and drivers alongside with the PHY devices/drivers.
