[060/136] drm/i915: Fix typo for wrong LVDS clock setting on IGDNG

[Greg KH]

2.6.31-stable review patch.  If anyone has any objections, please let us know.

------------------
From: Zhenyu Wang <zhenyuw@xxxxxxxxxxxxxxx>

commit b09aea7fb38f328c02e9f9b79617cabed02455e4 upstream.

New register for PCH LVDS on IGDNG should be used.
This is a copy-n-paste typo. This fixes possible dual
channel LVDS panel failure on IGDNG.
