Bug description:
[Impact]
BOE 2270 panel is used by several models of ThinkPads.
This brightness can not be controlled by default PWM.
[Fix]
The panel claims both PWM and AUX supports.
But actually PWM works on SDR mode, AUX works on HDR mode.
Intel i915 driver got a new SDR support to use PWM by maintainer, still in
upstream review.
To fix this on certain project, use a quirk first to fix this.
The maintainer's fix can be backported in future.
[Test Case]
Backlight brightness can be changed.
[Regression Potential]
Low,
Fix for specific panel ID, no effects for others.
Since this is temporary quirk, it will go to oem-5.6 only.
