Subject: [PATCH] net: mdio: of_mdiobus_register(): fall back to mdiobus_register() for !CONFIG_OF

If CONFIG_OF is not set, make of_mdiobus_register() call
mdiobus_register() instead of returning -ENOSYS.

This way, we can just call of_mdiobus_register() from all DT-enabled
drivers to handle the compat cases.
