[RFC v4 14/25] drm/fb-helper: Remove struct drm_fb_helper_connector

["Noralf Trønnes" <noralf@tronnes.org>]

No need to maintain a list of registered connectors. Just use the
connector iterator.

TODO: Remove:
- drm_fb_helper_add_one_connector()
- drm_fb_helper_single_add_all_connectors()
- drm_fb_helper_remove_one_connector()
