drm/msm/dpu: initialize dpu encoder and connector for writeback
Initialize dpu encoder and connector for writeback if the
target supports it in the catalog.
changes in v2:
- start initialing the encoder for writeback since we
have migrated to using drm_writeback_connector_init_with_encoder()
- instead of checking for WB_2 inside _dpu_kms_initialize_writeback
call it only when its WB_2
- rebase on tip of msm-next and remove usage of priv->encoders
changes in v3:
- none
changes in v4:
- fix copyright years order
