The recent commit added Jack controls to Dell Dock, but it added with
iface = SNDRV_CTL_ELEM_IFACE_CARD. Unfortunately this doesn't match
with the changes in user-space UCM profile, which expects iface =
SNDRV_CTL_ELEM_IFACE_MIXER as default. This mismatch resulted in the
non-working profile, and the Dell Dock is gone on pipewire /
PulseAudio after the kernel update.
Fix the regression by adjusting the iface of the new ctl elements to
*_MIXER.
