drm/rcar-du: Convert drm_atomic_helper_suspend/resume()

Browse Source 
convert drm_atomic_helper_suspend/resume() to use
drm_mode_config_helper_suspend/resume().

remove suspend_state field from the rcar_du_device
structure as it is no more required.

With this conversion, also drm_fbdev_cma_set_suspend_unlocked()
will left with no consumer. So this function can be removed.
