drm/i915: Move all ring resets before setting the HWS page
In commit a51435a3137ad8ae75c288c39bd2d8b2696bae8f Author: Naresh Kumar Kachhi <naresh.kumar.kachhi@intel.com> Date: Wed Mar 12 16:39:40 2014 +0530 drm/i915: disable rings before HW status page setup we reordered stopping the rings to do so before we set the HWS register. However, there is an extra workaround for g45 to reset the rings twice, and for consistency we should apply that workaround before setting the HWS to be sure that the rings are truly stopped.
