drm/amd/display: add a debugfs interface for the DMUB trace mask
For features that are implemented primarily in DMUB (e.g. PSR), it is
useful to be able to trace them at a DMUB level from the kernel,
especially when debugging issues. So, introduce a debugfs interface that
is able to read and set the DMUB trace mask dynamically at runtime and
document how to use it.
