drm/amd/display: Indicate when custom brightness curves are in use
[Why]
There is a `scale` sysfs attribute that can be used to indicate when
non-linear brightness scaling is in use. As Custom brightness curves
work by linear interpolation of points the scale is no longer linear.
[How]
Indicate non-linear scaling when custom brightness curves in use and
linear scaling otherwise.
