Looks good thanks Andrew. I do wonder if we could define a common
mii_bus_platform_data structure eventually which is comprised of these
two members (if nothing else) and maybe update the common
mdiobus_register() code path to look for these members. If a subsequent
platform data/device MDIO bus shows up we could do that at that time.

Thanks!
