drm/amd/display: Extend secure display to support DisplayCRC mode
[Why]
For the legacy secure display, it involves PSP + DMUB to confgiure and
retrieve the CRC/ROI result. Have requirement to support mode which all
handled by driver only.
[How]
Add another "DisplayCRC" mode, which doesn't involve PSP + DMUB.
All things are handled by the driver only
