ALSA: hda/realtek - Avoid multi-ios conflicting with multi-speakers
When a machine has multiple speakers, we don't need to create the
controls for multi-ios. Check the number of primary outputs beforehand.
Note that this workaround might not work always with new codecs in
future; this assumes that both speakers and multi-io jacks share the
same mixers/DACs. If they are routed with different mixers, the
individual mixer controls should be needed. But, so far, this doesn't
happen with the existing ALC codecs.
