Move headset jack registration to the codec/machine specific initialization. Having the jack registration in machine init causes that the jack device gets initialized but not registered since the sound card is registered before the jack. Moving jack registration to device initialization will register the jack device along with all other devices associated to the card when the card is registed. As a consequence of jack device registered properly, the jack is detected as an input device.
