The driver is currently using ALC269_FIXUP_DELL4_MIC_NO_PRESENCE for
the Latitude 7520, but this fixup chain has some issues:

 - The internal mic is really loud and the recorded audio is distorted
   at "standard" audio levels.

 - There are pop noises at system startup and when plugging/unplugging
   headphone jacks.
