drm/amd/display: Add interface to capture power feature status for debug logging 



[Why]
The status of various power features is often important information when
debugging certain issues, such as underflow. This info helps to
narrow down the potential sources of errors.

[How]
Add dc interface to capture power feature enablement status.
