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

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 second patch is just to fix the orientation of the panel.

Changes since v1:
 - rebased on drm-tip
 - squashed patch 1 & 2
 - picked up Reviewed-by from Hans de Goede (thanks for the review)

Changes since v2:
 - rebased on drm-tip
 - updated commit message

When v2 was initially sent [3] Ville Syrjälä suggested that it might be
a good idea to use the ACPI _DDC method instead to get the EDID, to
cover a wider range of hardware. Unfortunately, it doesn't seem
available on GPD Win Max, so I think this work should be done
independently, and this patch series considered separately.

Change since v3:
 - edits following Jani's review:
    - The EDID from the opregion is now only used as a fallback: if we
      cannot get any edid from the edp connector, then we attempt to get
      it from the opregion. This works for the GPD Win Max.
    - all other remarks should have been taken into account
 - rebased on drm-tip
 - added Co-developed-by
 - reordered signed-off-by and reviewed-by in second patch (thanks
   Maarten!)

Changes since v4:
 - checkpatch.pl fixes
 - rebased on drm-tip
 - Note: patch #1 is incomplete, still missing Jani's signed-off-by
