drm/msm/dpu: add the writeback connector layer

Browse source

Introduce the dpu_writeback module which serves as the
interface between dpu operations and the drm_writeback.

This module manages the connector related operations for
dpu writeback.

changes in v2:
	- start using drm_writeback_connector_init_with_encoder()
	- drop unnecessary arguments from dpu_writeback_init()
	- rebase on msm-next tip and remove usage of priv->connectors

changes in v3:
	- none

changes in v4:
	- none

changes in v5:
	- store the drm_enc in the dpu_wb_conn to be used while
	  using dpu_encoder APIs
