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.
