Well, it helps building but that's only part of the issue - we've still
got registration problems and if we were using the API in anger we would
need things like clk_set_rate() to actually work.  It's not just a case
of simply enabling and disabling clocks (which can be stubbed out pretty
effectively), audio generally needs to manage the clock rates too.
