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. Along with this
Pixel replication and Odd pixel considerartions are also required.

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.
