This adds some helpers for accessing non-phy MDIO devices. They are
analogous to phy_(read|write|modify), except that they take an mdio_device
and not a phy_device.

I am not too experienced with coccinelle, so pointers would be
appreciated. In particular, is it possible to convert things like
bus = mdiodev->bus;
addr = mdiodev->addr;
mdiobus_foo(bus, addr, ...);
in a generic way?
