drm/msm/dpu: add an API to setup the CDM block for writeback

Add an API dpu_encoder_helper_phys_setup_cdm() which can be used by
the writeback encoder to setup the CDM block.

Currently, this is defined and used within the writeback's physical
encoder layer however, the function can be modified to be used to setup
the CDM block even for non-writeback interfaces.

Until those modifications are planned and made, keep it local to
writeback.

changes in v3:
	- call bind_pingpong_blk() directly as disable() is dropped
	- add dpu_csc10_rgb2yuv_601l to dpu_hw_util.h and use it
	- fix kbot error on the function doc
	- document that dpu_encoder_helper_phys_setup_cdm() doesn't handle
	  DPU_CHROMA_H1V2

changes in v2:
	- add the RGB2YUV CSC matrix to dpu util as needed by CDM
	- use dpu_hw_get_csc_cfg() to get and program CSC
	- drop usage of setup_csc_data() and setup_cdwn() cdm ops
	  as they both have been merged into enable()
	- drop reduntant hw_cdm and hw_pp checks
