drm/msm/dpu: reserve cdm blocks for writeback in case of YUV output

Browse source

Reserve CDM blocks for writeback if the format of the output fb
is YUV. At the moment, the reservation is done only for writeback
but can easily be extended by relaxing the checks once other
interfaces are ready to output YUV.

changes in v3:
	- squash CDM disable during encoder cleanup into this change

changes in v2:
	- use needs_cdm from topology struct
	- drop fb related checks from atomic_mode_set()
