Now the suspend/resume methods no longer need to look at internal driver state, the dpms and started fields in the shmob_drm_crtc structure can be removed, as well as the shmob_drm_crtc_dpms() wrapper. After this, shmob_drm_crtc_atomic_{en,dis}able() became just wrappers around shmob_drm_crtc_st{art,op}(), so inline the latter.
