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

Browse Source 
This reverts commit cda45b715d which is
commit 3550bba25d5587a701e6edf20e20984d2ee72c78 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.
