[PATCH v7 5/9] drm: writeback: drop excess connector initialization functions

[Dmitry Baryshkov <dmitry.baryshkov@oss.qualcomm.com>]

Now as all drivers have been converted to
drm_writeback_connector_init_with_encoder(), drop
drm_writeback_connector_init() and drm_writeback_connector::encoder
field, they are unused now.

- * @wb_connector: Writeback connector to initialize

- * This function creates the writeback-connector-specific properties if they

- *
- * Drivers should always use this function instead of drm_connector_init() to
- * set up writeback connectors.
- *
- * Returns: 0 on success, or a negative error code
