ALSA: hda/realtek: Add quirk for Dell Latitude 7520
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.
