Subject: [PATCH] ALSA: usb-audio: Add quirks for Dell WD19 dock

The WD19 family of docks has the same audio chipset as the WD15. This
change enables jack detection on the WD19.

We don't need the dell_dock_mixer_init quirk for the WD19. It is only
needed because of the dell_alc4020_map quirk for the WD15 in
mixer_maps.c, which disables the volume controls. Even for the WD15,
this quirk was apparently only needed when the dock firmware was not
updated.
