[PATCH v2 5/6] drm/rcar_du: pass possible_crtcs as parameter for drm_writeback_connector

[Abhinav Kumar]

As part of this series, drm_writeback_connector_init() allows
passing possible_crtcs as a parameter so that the API can
internally create and setup the encoder.

Pass possible_crtcs parameter for drm_writeback_connector_init()
for rcar-du writeback driver.

changes in v2:
  - pass possible_crtcs parameter for drm_writeback_connector_init()
