[v4,08/12] cpufreq: Add stub for cpufreq_update_policy()

Commit Message

cpufreq stubs out some functions when CONFIG_CPU_FREQ=n , but
cpufreq_update_policy() is not among them. The throttler driver
(https://patchwork.kernel.org/patch/10453351/) uses cpufreq as one
possible throttling mechanism, but it can still be useful without
cpufreq. Stubbing out cpufreq_update_policy() allows the throttler
driver to be built without ugly #ifdef'ery when cpufreq is disabled.
