I still wasn't happy with this approach, so I bugged Arnd and we
discussed some options.  So, I think I've got a better solution that
doesn't change the signature of of_xlate.  Instead it allows of_xlate
to return an error code and still have multiple banks referring to the
same gpio_chip.

I've just posted the series.  Can you try it out and make sure it
works for you?
