When the Device Tree node specified is NULL, fall back to mdiobus_register(). We have a number of drivers having a similar pattern which is: if (np) of_mdiobus_register() else mdiobus_register() so incorporate that behavior within the core of_mdiobus_register() function. This is also consistent with the stub version that we defined when CONFIG_OF=n.
