drm/amd/display: Add a new dcdebugmask to allow turning off brightness curve

2025-03-05T15:42:57Z

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.
