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.
