In some cases, set_sensor_state and get_sensor_input are more related to the joypad driver, e.g. in desktop platforms where sensors are associated rather with the joypad. If input driver supports the sensors, it is still preferred. Placeholder inserted for all input drivers, no functionality added yet.
