Modified Files:
        src/sys/dev/clk: clk.c clk.h clk_backend.h

Log Message:
As discussed on tech-kern@ 10 days ago, add a clk_round_rate() method,
which returns the rate that would be used by this clock if clk_set_rate()
was called. Used by drivers (or other clocks) which have their own divider
and need to know the parent's clock capabilities to compute the best
parameters.
