Revert "gpiolib: of: Introduce hook for missing gpio-ranges"

This reverts commit cda45b71 which is
commit 3550bba2 upstream.

It breaks the Android kernel ABI and is not needed for Android devices,
so it is safe to revert for now.  If it is determined that it is needed
in the future, it can be brought back in an abi-preserving way.
