Can we please stop messing with the function prototypes? So you prefer
passing a struct to clk_register which is fine and yes, it may have
advantages. But do we really need to change the prototype? Why can't we
just add a new function?

I am generally open to do these changes, but we have come to the point
where people actually want to *use* the clock framework instead of
rebasing their stuff onto the latest patches.
