From: Ville Syrjälä <[email protected]> This async flip vt-d w/a was moved to a different place in commit 7d396cacaea6 ("drm/i195: Make the async flip VT-d workaround dynamic") but the drm-intel-fixes cherry-pick commit b2d73debfdc1 ("drm/i915: Extend the async flip VT-d w/a to skl/bxt") resurrected the original code as well. So now we have this w/a in two places. Remove the resurrected zombie code.
Not done as a revert to hopefully prevent any kind of automagic stable backport.
