In the V2:
Because the patch is not merged to mainline kernel yet, it is still in the audio
tree, so added the git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound.git
in the V2.

the headset-mic can't be detected after we plug the headset into the audio jack

Apply the fixup of ALC255_FIXUP_DELL1_MIC_NO_PRESENCE.

[Test Case]
Boot up the system
plug the headset into the audio jack
The audio device selecting dialogue will show up
selecting headset-mic icon, then rerord sound from headset-mic, it works well.

[Regression Risk]
Low. this patch only applies to specific dell machines which have the same pin config
as defined in the patch.

  ALSA: hda/realtek - add two more pin configuration sets to quirk table
