drm/msm/dpu: add DSC 1.2 hw blocks for relevant chipsets

Add DSC 1.2 hardware blocks to the catalog with necessary sub-block and
feature flag information.  Each display compression engine (DCE) contains
dual DSC encoders so both share same base address but with its own
different sub block address.

changes in v4:
-- delete DPU_DSC_HW_REV_1_1
-- re arrange sc8280xp_dsc[]

changes in v4:
-- fix checkpatch warning

changes in v10:
-- remove hard slice from commit text
-- replace DPU_DSC_NATIVE_422_EN with DPU_DSC_NATIVE_42x_EN
-- change DSC_BLK_1_2 .len from 0x100 to 0x29c

changes in v11:
-- remove comment at DSC_BLK_1_2 marco
