I don't understand how gated jack work, but those headset mic in alc668
dell-headset-multi does not  use its own pin sense and won't need to enable
unsol event of the headset mic node.

As pulseaudio don't expect jack kctl can be repesent the state of headphone
and mic

This force the driver to create a headset mic kctl which is just a copy of
the headphone jack kctl
