From: Clint Taylor <clinton.a.taylor@intel.com>
Latest version of the "CHV DPIO programming notes" no longer requires writes
to TX DW 11 to fix a +2UI interpair skew issue. The current code from
April 2014 was actually causing additional skew issues between all
TMDS pairs.

You saved me lots of time testing the same change on DP. I will probably still put it on a scope to confirm the improvement.
