Make clock rate recalculation easy by having a re-calculate
function for each clock.
The existing functions for calculation of output rates of PLL
and PLL-derived sysclks have been convered to the new
re-calculate API.
A new function is introduced to take care of rate
(re)calculation for leaf clocks.
