ARM64: dts: rk3399: add clock-latency-ns for each opp

We may miss clock-latency-ns when disable some opps, then cpufreq
will fallback to performance governor, so add clock-latency-ns for
each opp to make disable opp easy.

code as below:
drivers/cpufreq/cpufreq.c:2010
if (policy->governor->max_transition_latency &&
    policy->cpuinfo.transition_latency >
    policy->governor->max_transition_latency) {
	if (!gov)
        	return -EINVAL;
	else {
      		pr_warn("%s governor failed, too long transition latency of HW,
			fallback to %s governor\n",
                	policy->governor->name, gov->name);
        	policy->governor = gov;
	}
}
