From: Ranjani Sridharan <ranjani.sridharan@xxxxxxxxxxxxxxx>
When there is only one input/output format specified in topology, there
is no need to search for a matching format, simply pick the available
one. This is in preparation to modify and split the selection logic for
the input and output audio formats.
