Bug description:
[Impact]
Brightness on HP DreamColor panel, which can be found on new HP Zbook
Studio, cannot be changed.
[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.
