Add of_mdio_find_bus() which allows an mii_bus to be located given its associated the device tree node. This is needed by the follow-on patch to add a driver for MDIO bus multiplexers. The of_mdiobus_register() function is modified so that the device tree node is recorded in the mii_bus. Then we can find it again by iterating over all mdio_bus_class devices. Because the OF device tree has now become an integral part of the kernel, this can live in mdio_bus.c (which contains the needed mdio_bus_class structure) instead of of_mdio.c.
