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.
