The dev_token field is used by the audio DSP to notify the USB offload driver of which card and PCM index to enable playback on. Separate this into a dedicated API, so the USB backend can set the dev_token accordingly. The audio DSP does not utilize this information until the AFE port start command is sent, which is done during the PCM prepare phase.
