gpio: of: Fix hard-assigned valid_mask for OF case
The recent refactoring to break out OF code to its own file contained a bug letting the need_valid_mask be overridden by the need of the device tree range check, and if there were no ranges, but device tree was active and the reserved GPIO used in another way, things likely crash.
