drm/amd/display: Adjust dm to use supported interfaces for setting multiple crc windows

Browse Source 
[Why & How]
We actually have the capability to calculate independent CRC for 2 crc window
at the same time. Extend dm with the capability by having array to
configure/maintain multiple crc windows. Add the flexibility but use 1st CRC
instance only for now. Can change to use the 2nd CRC instance if needed.
