drm/msm/dpu: introduce the dpu_encoder_phys_* for writeback

Browse Source 
Introduce the dpu_encoder_phys_* for the writeback interface
to handle writeback specific hardware programming.

changes in v4:
	- squash the encoder_phys_wb bits from [1]
	- since its a trivial change of a previously acked change
	  preserving the ack
