No need to patch AMD-provided drivers/gpu/drm/radeon/atombios.h

This is partial revert of commit 9404c9c392d5 ("Fix misspelling of "should"
and "shouldn't" in comments"). According to Dave Airlie:

	"Can we drop any cleanups to atombios.h? This file comes from
	AMD and we normally drop it into place, so they just get overwritten
	next time."
