    Pull more power management updates from Rafael Wysocki:
     "These update the CPPC cpufreq driver and intel_pstate (which involves
      updating the cpufreq core and the schedutil governor) and make
      janitorial changes in the ACPI code handling processor objects.
    
      Specifics:
    
       - Rework the passive-mode "fast switch" path in the intel_pstate
         driver to allow it receive the minimum (required) and target
         (desired) performance information from the schedutil governor so as
         to avoid running some workloads too fast (Rafael Wysocki).
    
       - Make the intel_pstate driver allow the policy max limit to be
         increased after the guaranteed performance value for the given CPU
         has increased (Rafael Wysocki).
    
       - Clean up the handling of CPU coordination types in the CPPC cpufreq
         driver and make it export frequency domains information to user
         space via sysfs (Ionela Voinescu).
    
       - Fix the ACPI code handling processor objects to use a correct
         coordination type when it fails to map frequency domains and drop a
         redundant CPU map initialization from it (Ionela Voinescu, Punit
         Agrawal)"
