x86/cpufreq: add a new driver interface, setpolicy()

In order to better support future Intel processors, intel_pstate
changes to use percentage values to tune P-states. The setpolicy
driver interface is used to configure the intel_pstate internal
policy. The __cpufreq_set_policy needs to be intercepted to use
the setpolicy driver if it exists.
