drm/amd/display: Expand dc to use 16.16 bit backlight
[Why] We want to increase precision for backlight setting.
But DC interface takes 8 bit backlight level value only.
[How] DMCU already takes 16 bit backlight level.
Expand the DC interface to take 16.16 bit value.
Max 32 bit backlight value (0xFFFF) will represent
max backlight (100%)
