why isn't this an actual clock phandle ? Driver could, then, use
clk_get_rate() to figure this one out. You could just use a fixed clock
here to satisfy the clock API.

I've actually been working on getting the da8xx ohci driver working with 
device tree. It has similar clock issues (in fact, the ohci clock is a 
child of the musb clock). Petr, give me a day or two and will have post 
some patches. It will have a clock that can be used here for clk_get_rate().
