Summarizing, this shouldn't be required on any platform supporting
OpRegion. And none of the really old machines I have here seem to
require it either. Hence I'm inclined to just rip it out.

But in case that there are really firmwares out there that clobber the
hw state, replace it with a call to intel_modset_check_state. This
will ensure that we catch any issues as soon as they happen.
