igfx: coerce x250 display to work one wants bpc=8, the other bpc=6, not sure what to do there x250: hwgc doesn't work, checkgtt fails, modesetting multiple times will garble picture, edid gets snarfed sometimes, most times not; brightness seg(1) hack doesn't work. x240: all works, except minidp (no way to be sure, same for x250 and desktop) desktop: hdmi still good, minidp doesn't work
