[Fix] Let DRM know the panel should use DPCD instead of PWM to control backlight. [Test] With the patch applied, we can change the brightness on HP Zbook Studio. [Regression Potential] If there's any panel in the quirk list depends on checking brightness control capability then this change will have an impact. However it's rather unlikely because it defeats the purpose of the quirk list.
