Bug description:
  [Impact]
  On this Dell machine (codename: turtle bay), the microphone always shows up
  in the sound-setting even there is no microphone plugged in.

  [Fix]

  Without this fix, the pin will be regarded as microphone, and the jack name
  is "Mic Phantom", it is always on in the pulseaudio even nothing is plugged
  into the jack. So the UI is confusing to users since the microphone always
  shows up in the UI even there is no microphone plugged.

  After adding this flag, the jack name is "Headset Mic Phantom", then
  the pulseaudio can handle its detection correctly.

  
  [Test Case]
  After booting up the system, and without plugging anything in the audio combo
  jack, there is nothing in the input tab of sound-setting, then plug a headset
  in the jack, the what-did-you-plug-in dialogue pops up, users can select headset
  mic from UI, and headset-mic shows up in the sound-setting, we can record sound
  via headset-mic

  
  [Regression Potential]
  Very low, since this patch is specific for ALC255_FIXUP_DELL_HEADSET_MIC which is
  only used by Dell precision 3630 by now.
