This bit is better added to the CODEC driver since it'll apply to any
system where there's this clock rate (someone else could come in and add
other rates, no need to do that yourself though it'd be nice of course).
I could do it.
It looks like these constraints are already in the wm8731 driver. I will
wait for more comments and then I will send a v2 without this part.
Thanks and best regards,
Codrin
