Subject: [PATCH] Add GPD Pocket 2 04/17/2020 BIOS to drm_orientation_quirks

From: Mark Dietzer <git@...idian.net>

Add missing BIOS version to drm_orientation_quirks for the
GPD Pocket 2

---
This seems to be the latest available offical BIOS for this machine.
I can no longer find it hosted by GPD themselves, but did find it
at least archived (on archive.org) here:
https://archive.org/download/gpd-pocket-2-drivers-and-os/driver-and-bios/

Testing and confirmed working on my own GPD Pocket 2.

Below is the output of "dmideocde", specifically the BIOS section

Handle 0x0000, DMI type 0, 24 bytes
