Subject: [PATCH 2/3 v6] drm: atmel_hldc: Use generic drm_connector_register_all() helper

This driver used to have its own implementation of connector_register_all()
which actually was taken as a prototype of drm_connector_register_all().

Now when drm_connector_register_all() exists reusing it here.

Changes v5 -> v6:
 * Only substitute its own atmel_hlcdc_dc_connector_plug_all().
   drm_connector_unregister_all() is already used there since
   222b90943446 "drm/atmel: Fixup drm_connector_/unplug/unregister/_all"

No changes v4 -> v5.

No changes v3 -> v4.

Changes v2 -> v3:
 * Updated title with capital after colon
 * Added ack from Boris

No changes v1 -> v2.
