drm/amd/display: Update LSDMA commands to explicitly handle DCC fields

Browse source

[Description]
- Previously linear copy commands for LSDMA assumed no DCC
- Update so that there is explicit assignment for DCC related fields
	- Caller can 0 out the fields if DCC is not used
- For linear copy command don't subtract 1 from the count - this will
  be done at a lower layer
