Now that we no longer have continuous mode we always want to start the sensor on the first atomisp_start_streaming() call and stop it on the first atomisp_stop_streaming() call. Remove atomisp_sensor_start_stream() which returned the number of streams which should be active before starting the sensor and always start/stop the sensor directly.
