Change the type of variable from "unsigned long" to "u64".
This avoids the overflow while clock rate calculating.

Thanks, applied to Tegra's for-3.7/fixes-for-rc2 branch.

Prashant, this same bug was found before in another round_rate() or
similar function, and I'd asked you to audit the entire Tegra clock
driver for any similar issues. Could you (and/or Mark) please take
another look at the entire driver to make sure we don't keep finding
this issue clock-by-clock. Thanks.
