of: kill off of_can_translate_address
of_can_translate_address only checks some conditions for address translation, but does not check other conditions like having range properties. The checks it does do are redundant with __of_address_translate. The only difference is printing a message or not. Since we only have a single caller that does the full translation anyway, just remove of_can_translate_address and quiet the error message.
