drm/amd/display: Handle Content protection property changes
[Why]
We need to manage the content protection property changes for
different usecase, once cp is DESIRED we need to maintain the
ENABLED/DESIRED status for different cases.
[How]
1. Attach the content_protection property
2. HDCP enable (UNDESIRED -> DESIRED)
call into the module with the correct parameters to start
hdcp. Set cp to ENABLED
3. HDCP disable (ENABLED -> UNDESIRED)
Call the module to disable hdcp.
3. Handle Special cases (Hotplug, S3, headless S3, DPMS)
If already ENABLED: set to DESIRED on unplug/suspend/dpms,
and disable hdcp
Then on plugin/resume/dpms: enable HDCP
