I'm struggling to think of a better name for this right now but the _fs
name is making me think of the MCLK/SYSCLK rate rather than the BCLK
rate - lots of clocks get specified as a multiple of the sample rate so
it's not jumping out which clock.  The best I can come up with is
_bclk_fs() but perhaps there are better ideas?  Or should we pass in a
clock ID (and provide standard defines for things like BCLK) so it can
apply to any clock?

Though looking at your ACPI ID patch perhaps pwgen can give us some good
ideas :)
