SRU justification:

[Impact]
OLED backlight is not supported by the current kernel.
Sometimes the screen goes to black screen when enabled dpcd backlight support.

[Fix]
Fix max brightness value and enable dpcd to support adjusting brightness on OLED.
Force enable backlight again to fix black screen issue.

[Test]
Verified on several laptops, backlight on and brightness is adjusted.

[Regression Potential]
Medium, change is limited to specific hardware feature.
Verified on no dpcd support laptops, no regression found yet.
