drm/msm/dpu: add support to allocate CDM from RM

Browse source

Even though there is usually only one CDM block, it can be
used by either HDMI, DisplayPort OR Writeback interfaces.

Hence its allocation needs to be tracked properly by the
resource manager to ensure appropriate availability of the
block.

changes in v2:
	- move needs_cdm to topology struct
