The naming of the existing 'config_stream' callback does not map well with any of ALSA/ASoC concepts. This patch renames it as 'params_stream' to be more self-explanatory. A new 'free_stream' callback is added in case any resources allocated in the 'params_stream' stage need to be released. In the SOF implementation, this is used in the hw_free case to release the DMA channels over IPC.
