drm/amd/display: Add a new dcdebugmask to allow turning off brightness curve
Upgrading the kernel may cause some systems that were previously not using
a firmware specified brightness curve to use one.
In the event of problems with this curve (for example an interpolation
error) add a new dcdebugmask value that can be used to turn it off. Also
add an info message to show that custom brightness curves are currently in
use.
