append_dai_type should be set to true in any situation that would
result in multiple DAI links existing on a single SoundWire bus,
because the legacy naming used only the bus number to make things
unique. The current code handles this by looking for codecs with
multiple dai_info structs and looking for buses that include multiple
types of device on them. The first of these assumes that all DAIs on a
given device would be in use. The second, with dissimilar aggregation
now being supported, isn't really an accurate check either since those
devices could be aggregated into a single DAI link.

Move the handling for this flag over to the new parsing code and
simplify things a little by looking directly for SoundWire links
that will contain multiple DAI links to set the flag. These changes
should not cause any change in behaviour for any currently supported
systems.
