    drm/i915/skl: Enable DDI-E · 2800e4c2
    Rodrigo Vivi authored
    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.
