Call the clock's round_rate op, if it exists, before calling the set_rate op. This will help later when dvfs is added, dvfs needs to know what the final rate will be before the frequency changes. Also requires fixes to the round rate functions to ensure calling round rate and then set rate will not cause the frequency to be rounded down twice. When picking clock divider values, the clock framework picks the closest frequency that is lower than the requested frequency. If the new frequency calculated from the divider value is rounded down, and then passed to set_rate, it will get rounded down again, possibly resulting in a frequency two steps lower than the original requested frequency. Fix the problem by rounding up when calculating the frequency coming out of a clock divider, so if that frequency is requested again, the same divider value will be picked.
