Subject[061/136] drm/i915: Fix SSC frequence for IGDNG
2.6.31-stable review patch.  If anyone has any objections, please let us know.

------------------
From: Zhenyu Wang <zhenyuw@linux.intel.com>

commit 339e5a4c78041cd7b473ddf0a81eb06a131127bb upstream.

IGDNG LVDS SSC uses 120Mhz freq. This fixes one
1600x900 LVDS panel black issue on IGDNG with SSC enabled.
