[PATCH 0/7] Add support for 3 VDSC engines 12 slices

[Ankit Nautiyal]

For BMG 3 VDSC engines are supported and each pipe can then support
3 slices. For Ultra joiner cases for modes like 8k at 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:
-Dropped patches for pixel replication and odd pixel removal.
