[PATCH v4 12/15] drm/msm/dpu: plug-in the cdm related bits to writeback setup

[Abhinav Kumar]

To setup and enable CDM block for the writeback pipeline, lets
add the pieces together to set the active bits and the flush
bits for the CDM block.

changes in v2:
	- passed the cdm idx to update_pending_flush_cdm()
	  (have retained the R-b as its a minor change)
