Ideally we'd be able to set up a route between the two DAIs and then
have the framework arrange for data to go from one to the other.  There
are hardware limitations in being able to do this - you either need ASRC
in the hardware or you need to be able to ensure that all the clocks are
synchronous.  Right now you have to bounce everything through the
application layer.
