cpufreq: Add new helper function returning cpufreq policy
cpufreq_cpu_get_raw() gets cpufreq policy only if the CPU is in
policy->cpus mask, which means the CPU is already online. But in some
cases, the policy is needed before the CPU is added to cpus mask. Add a
function to get the policy in these cases.
