Bug description:
[Impact]
Cannot change brightness on HP ZBook Fury with certain panel.
[Fix]
Add the panel to DPCD quirk table to use DPCD to control the panel
backlight.
[Test]
Changing backlight sysfs doesn't change the display brightness.
With the patch applied, changing sysfs backlight can really change the
display brightness.
[Where problems could occur]
This fix is specific to a single panel, so it's not likely to cause any
regression to other devices.
