I was thinking about this. I think the common clock fwk should let the
set_parent ops "return" the rate of the clock in addition to passing the
rate of the parent in.
Say this is a divider clock and some one changes the parent. The cached
"rate" of the clock in the clock fwk is no longer correct. So, the clock
fwk should also add a "*new_rate" param to set parent ops.
