[Intel-gfx] [PATCH 2/7] drm/i915: Assume we implement WaStripsFansDisableFastClipPerformanceFix:snb

[ville.syrjala at linux.intel.com]

From: Ville Syrjälä <ville.syrjala at linux.intel.com>

Based on the name, the workaround we implement is
WaStripsFansDisableFastClipPerformanceFix. Unfortunately there's no
description in the w/a database, so this is just a guess.
