drm_fb_helper_{add,remove}_one_connector() and drm_fb_helper_single_add_all_connectors() are dummy functions now and serve no purpose. Hence remove their calls.
This is the preparatory step for removing the drm_fb_helper_{add,remove}_one_connector() functions from drm_fb_helper.h
This removal is done using below sementic patch and unused variable compilation warnings are fixed manually.
