This seems like the wrong way to implement this. How about:
of_mdiobus_register(), when it loops over the children, looks for the
new property. If found, it passed dev-id to of_mdiobus_register_phy().
That passes it to get_phy_device(). I think get_phy_device() can then
set the ID in c45_ids, before passing it to
get_phy_id(). get_phy_c45_ids() will first look at devices in package
and can add further devices to c45_ids. It will then probe both those
found, and the static one you added.
