SSI will be used as normal SSI or as clock parent SSI. Therefor, rsnd driver wants to control SSI and parent SSI separately. Otherwise it can't use Playback/Capture in the same time. And it has been done by c2dc47d5cf("ASoC: rsnd: rsnd_dai_stream has each mod's status insted of rsnd_mod") before.
OTOH, rsnd driver doesn't want to control CTU/MUX/DVC/SSIU/SSI in separately. Otherwise, these will be re-initialized during playing if MUX merges 2 sounds. Because of these picky reasons, this patch re-defines status on each mod, and add new parent_ssi_status on rsnd_dai_stream.
