cpufreq: don't call cpufreq_update_policy() on CPU addition
cpufreq_update_policy() is called from two places currently. From a
workqueue handled queued from cpufreq_bp_resume() for boot CPU and
from cpufreq_cpu_callback() whenever a CPU is added.
The first one makes sure that boot CPU is running on the frequency
present in policy->cpu. But we don't really need a call from
cpufreq_cpu_callback(), because we always call cpufreq_driver->init()
(which will set policy->cur correctly) whenever first CPU of any
policy is added back. And so every policy structure is guaranteed to
have the right frequency in policy->cur.
