Add functions "Headset" and "Mic" to the control "Jack Function" for activating and de-activating codec input pin LINE1L which is connected to the mic pin of 4-pole Nokia AV connecter.

Note there is no mic bias voltage management here since bias is coming from Nokia ASIC and driver for it is not in mainline.
