drm/amd/display: Implement support for backlight optimization
- Add functionality to get real hw backlight level as opposed to user
level, meaning the level that takes into account backlight ramping
over time and backlight reduction due to Varibright
- Add backlight optimization which allows for a second OS state
that is able to control ABM
