drm/amd/display: Cap OLED brightness per max frame-average luminance
commit 4fd17f2ac0aa4e48823ac2ede5b050fb70300bf4 upstream.
[Why]
For OLED eDP the Display Manager uses max_cll value as a limit
for brightness control.
max_cll defines the content light luminance for individual pixel.
Whereas max_fall defines frame-average level luminance.
The user may not observe the difference in brightness in between
max_fall and max_cll.
That negatively impacts the user experience.
[How]
Use max_fall value instead of max_cll as a limit for brightness control.
