drm/nouveau: only runtime suspend by default in optimus configuration
commit b25b4427e9dfba073cf9bc86603956ed395eb6e3 upstream.
The intent was to only enable it by default for optimus, e.g. see the
runtime_idle callback. The suspend callback may be called directly, e.g.
as a result of nouveau_crtc_set_config.
