which is expected, but then we complain when we see that the HDMI port is still
active as we try to disable CRTCs at init time. But then we don't even see an
HDMI connector in your readout_hw_state() list... Can you try the patch below
to intel_display.c and see what happens? Maybe the VBT is telling us this port
is an eDP port, or the detect strap isn't correct.
