[PATCH v2 05/16] drm/msm/dpu: add cdm blocks to sc7280 dpu_hw_catalog

[Abhinav Kumar]

Add CDM blocks to the sc7280 dpu_hw_catalog to support
YUV format output from writeback block.

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
