drm/i915: Update Skylake DDI translation table for HDMI. 



When debuging an intermittent corrupted screen I suspected on DDI
translation table and checked we are out of date with the spec.

I'm not sure this will fix my bug yet, but it is always good to follow
the spec.

v2: Ville caught a switched i-boost value. Thanks!
