do not set crtc in vc4_output_set_mode

setting crtc is done in _tdm_vc4_display_commit_layer or
_vc4_output_make_atomic_request.
setting crtc is unnecessary in vc4_output_set_mode.
and if drm has capability of atomic commit,
setting crtc with extra buffer is not needed.
this patch makes to reduce gem memory usage.
