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.
