drm/i915: Broadwell DDI Buffer translation - more tuning
BDW display - DP buffer translation values changed to give better margin.
Further change to entry 6; set dword 0 bit 31=1.
Both changes were approved already but this one didn't landed BSpec yet
this is why it is in a separated patch. Making reviewer's life easier.
Also alowing separated tests and any future bisect that might be needed.
Reference: Predator r74080 / HSD 4394389
v2: Arthur noticed I was changing the wrong bit.
