Sorry, I forgot to mention in the notes, that I allowed setting a
zero ratio on purpose, in order to allow "unsetting" the bclk
ratio (since it only takes effect if it is positive). I'm not
sure if it will ever be necessary to do that in practice, but I
thought I'd allow it, since it has a valid effect.
