src/cpu/intel: Add sanity check for cpu turbo mode capability
It is proper to check cpu turbo mode capability after it is selected to be enabled. If processor exhibits the presence of hardware support for turbo, turbo global state will be updated with TURBO_ENABLE. Otherwise, TURBO_UNAVAILABLE is applied to turbo global state. TEST=Validated turbo state on GLK and WHL devices.
