ALSA: usb-audio: Add quirks for Dell WD19 dock
[ Upstream commit 4413665dd6c528b31284119e3571c25f371e1c36 ]
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.
