drm: Remove drm_fb_helper add, add all and remove connector calls

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.
