Wysocki" Modify cpufreq Kconfig to select schedutil as the default governor if the intel_pstate driver has been selected and SMP support is enabled (because schedutil depends on SMP). Also select schedutil as well as the performance governor from the intel_pstate Kconfig section to ensure the equivalence of the passive and active mode governor configuration options.
