Retrieve and store checksum_region's CRC data from the DC hardware in vline0 irq
handler. A new function amdgpu_dm_crtc_update_checksum_region_crc() is
implemented and hooked to CRTC callback for updating the latest CRC values
to the checksum CRC blob.

This commit creates checksum_region properties at CRTC initialization,
and update the new region during the atomic atomic. A new function
amdgpu_dm_crtc_set_secure_display_crc_source() is implemented to control
the state of CRC engine of DC hardware.

drm: Introduce CRTC checksum region and CRC properties
drm/amd/display: Create checksum_region properties and handle new
region update
drm/amd/display: Implement the retrieval of checksum_region's CRC data
a CRTC by calling
drm_crtc_create_checksum_region_properties() and hook its own
implementation on new CRTC function update_chechsum_region_crc() to update
the values of the CRC property for the incoming userspace request.

Check if there is a new ROI update during the atomic commit and process
it. A new function amdgpu_dm_crtc_set_secure_display_crc_source() is
implemented to control the state of CRC engine in hardware.

When the user requests for secure display ROI or CRC data, the
request will be blocked until the CRC result of current frame is
calculated and updated to secure display ctx in vline0 irq handler.
