This isn't signed off either.  Are we positive that none of the users
set the bitclock to something non-default - there are devices out there
which require an unusual bitclock (eg, where it's also used as the
master clock and so needs overclocking)?

Providing a default as this does is a definite win, but allowing it to
be overridden may be needed sometimes (rarely fortunately).  Leaving a
stub set_sysclk() that just sets a variable and then using that value
instead of calculating in hw_params() would get the best of both worlds.
