[CPUFREQ][1/4] cpufreq "cpu group" awareness: add policy->cpus
Save the "affected_cpu_map" used in SMT-aware drivers in struct
cpufreq_policy->(cpumask_t) cpus, and use it wherever possible. In
most cases, the ->get() function is only allowed to run on one CPU [the
one passed as argument] to keep code simpler, and as that code path
isn't executed often, and only root can do it anyway.
