[Intel-gfx] [PATCH 8/6] drm/i915/skl: Enable DDI-E
There are OEMs using DDI-E out there, so let's enable it. Unfortunately there is no detection bit for DDI-E So we need to rely on VBT for that. I also need to give credits to Xiong since before seing his approach to check info->support_* I was creating an ugly vbt->ddie_sfuse_strap in order to propagate the ddi presence info v2: Rebased as last patch in the series. since all other patches in this series are needed for anything working propperly on DDI-E.
