cpufreq: intel_pstate: Consolidate policy verification 

There is still some code duplication between intel_pstate_verify_policy()
and intel_cpufreq_verify_policy(), so avoid it by moving the common
code into a separate function and calling it from both these places.

No intentional functional impact.
