Add CDM blocks to the sc7280 dpu_hw_catalog to support
YUV format output from writeback block.
changes in v3:
- change the comment from sub-blk to clk for CDM
changes in v2:
- remove explicit zero assignment for features
- move sc7280_cdm to dpu_hw_catalog from the sc7280
catalog file as its definition can be re-used
