ACPI: video: Add DMI quirk for GIGABYTE GB-BXBT-2807
The GIGABYTE GB-BXBT-2807 is a mini-PC which uses off the shelf
components, like an Intel GPU which is meant for mobile systems.
As such, it, by default, has a backlight controller exposed.
Unfortunately, the backlight controller only confuses userspace, which
sees the existence of a backlight device node and has the unrealistic
belief that there is actually a backlight there!
Add a DMI quirk to force the backlight off on this system.
