cpufreq: allocate CPU masks dynamically
struct cpufreq_policy, including a cpumask_t member, gets copied in
cpufreq_limit_change(), cpufreq_add_cpu(), set_cpufreq_gov(), and
set_cpufreq_para(). Make the member a cpumask_var_t, thus reducing the
amount of data needing copying (particularly with large NR_CPUS).
