I can implement my own dummy codec where I do not perform
any actions since in our platform all modem controls and BT controls
are done @AP side. But I really do not understand why ASoC provides the
soc-utils dummy codec? The current version of the dummy codec is
useless since it blocks the stream creation: please refer to soc_new_pcm.
