Revert "pinctrl: bcm2835: implement hook for missing gpio-ranges"

This reverts commit ceb61ab2 which is
commit d2b67744 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.
