Subject: ALSA: hda/realtek - Add ALC3234 headset mode for Optiplex 9020m

From: Bastien Nocera <[email protected]>

commit afecb146d8d8a60a1dde9cdf570c278649617fde upstream.

The Optiplex 9020m with Haswell-DT processor needs a quirk for the headset jack at the front of the machine to be able to use microphones.

A quirk for this model was originally added in 3127899, but c77900e removed it in favour of a more generic version.

Unfortunately, pin configurations can changed based on firmware/BIOS versions, and the generic version doesn't have any effect on newer versions of the machine/firmware anymore.
