I've applied this but I'd rather see the code changed so that the BCLK
is set automatically by default and the explict divider configuration
disables that. This way we get the best of both worlds - most users
won't need to worry about the BCLK configuration but those that need to
configure it can do so. An awful lot of users don't really understand
audio hardware and find having to learn about which clock rates they
need and so on a bit of a learning curve.
