Introduce 'unconfigure' callback
The 'unconfigure' callback can be used to clean up the 'configured'
state of an Audio Path, for when it is desired to reset the streams,
and/or reload a different stream configuration.
To destroy the streams, we must attempt to force their PCMs
closed. Take note though, that if a PCM is being written to when
an unconfigure command is issued, system instability may occur.
