The value from raw_read_cntfrq_el0() could be large enough to cause overflow when multiplied by USECS_PER_SEC. To prevent this, both USECS_PER_SEC and hz can be reduced by dividing them by their GCD. This patch also modifies the return type of `timer_hz()` from `uint64_t` to `uint32_t`, assuming that in practice the timestamp counter should never be that fast.
