Current Renesas sound is supporting PIO fallback if it can't use DMA. In such case, it should remove all attached modules, but current driver is missing about CTU/MIX. Because current implement requests specific mod for remove. To avoid same things in future, this patch removes all mods, and re-connects SSI when PIO fallback case.
