PPC: e500: Only create dt entries for existing serial ports
When the user specifies -nodefaults he can tell us that he doesn't want any serial ports spawned by default. While we do honor that wish, we still create device tree entries for those non-existent devices. Make device tree generation depend on whether the device is actually available.
