drm/amd/display: Export full brightness range to userspace
[WHY]
Userspace currently is offered a range from 0-0xFF but the PWM is
programmed from 0-0xFFFF. This can be limiting to some software
that wants to apply greater granularity.
[HOW]
Convert internally to firmware values only when mapping custom
brightness curves because these are in 0-0xFF range. Advertise full
PWM range to userspace.
