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.
