It turned out that the topology ABI takes the standard PCM rate bits as is, and it means that the recent change of the PCM rate bits would lead to the inconsistent rate values used for topology. This patch reverts the original PCM rate bit definitions while adding the new rates to the extended bits instead. This needed the change of snd_pcm_known_rates, too. And this also required to fix the handling in snd_pcm_hw_limit_rates() that blindly assumed that the list is sorted while it became unsorted now.
