This patch changes .iface to SNDRV_CTL_ELEM_IFACE_MIXER whre _PCM or
_HWDEP was used in controls that are not associated with a specific PCM
(sub)stream or hwdep device, and changes some controls that got
inconsitent .iface values due to copy+paste errors.  Furthermore, it
makes sure that all control that do use _PCM or _HWDEP use the correct
number in the .device field.
