For BMG 3 VDSC engines are supported and each pipe can then support 3 slices. For Ultra joiner cases for modes like 8k@120 Hz we require ultrajoiner and 3 x 4= 12 slices. Add support for 3 VDSC engines and 12 DSC slices. Rev2: Rebase Rev3: -Add patch to account for pixel replication in pipe_src. -Fix kernel test bot warning. -Minor refactoring. Rev4: -Address review comments from last version. -Add BW consideration with pixel replication -Split Odd pixel handling in separate patches. Rev 5: -Use num_streams instead of dsc_split. Rev 6: -Drop patches for pixel replication and odd pixel removal. Rev 7: -Fix Hw readout for DSC in Patch#2, and rebase.
