drm/i915: Set guardband clipping workaround bit in the right register.
A previous patch, namely:
commit bf97b276ca04cee9ab65ffd378fa8e6aedd71ff6
Author: Daniel Vetter <daniel.vetter@ffwll.ch>
Date: Wed Apr 11 20:42:41 2012 +0200
drm/i915: implement w/a for incorrect guarband clipping
accidentally set bit 5 in 3D_CHICKEN, which has nothing to do with
clipping. This patch changes it to be set in 3D_CHICKEN3, where it
belongs.
The game "Dante" demonstrates random clipping issues when guardband
clipping is enabled and bit 5 of 3D_CHICKEN3 isn't set. So the
workaround is actually necessary.
