This patch series is for making the GPD Win Max display usable with

The GPD Win Max is a small laptop, and its eDP panel does not send an
EDID over DPCD; the EDID is instead available in the intel opregion, in
mailbox #5 [1]

The first two patches are based on Jani's patch series [2] adding
support for the opregion, with minimal changes. I've change authorship
for the first, but we can revert it.

The third patch is just to fix the orientation of the panel. For some
reason it does not work at boot when an external display is plugged, but
I doubt this is specific to this hardware.
