Most of the users of cpufreq_verify_within_limits() calls it for limiting with
min/max from policy->cpuinfo. We can make that code simple by introducing
another routine which will do this for them automatically.

This patch adds another routine cpufreq_verify_within_cpu_limits() and updates
others to use it.
