Lenovo reported that a new OLED panel needs dpcd support to
change screen brightness.

Add the panel ID in quirk list to support dpcd control.

Verified on hardware by Lenovo.

[Regression Potential]
Upstream fix, clean cherry-picked.
Add an ID only affected on specific hw.
Unstable branch already got this patch.
