drm/amd/display: Expose new CRC window property
[Why]
Instead of calculating CRC on whole frame, add flexibility to calculate
CRC on specific frame region.
[How]
Add few crc window coordinate properties. By default, CRC is calculated
on whole frame unless user space specifies the CRC calculation window.
