Pull more power management updates from Rafael Wysocki:
 "These fix cpufreq core and the pcc cpufreq driver, add per-policy
  boost support to cpufreq and add Georgian translation Makefile
  LANGUAGES in cpupower.

  Specifics:

   - Add Georgian translation to Makefile LANGUAGES in cpupower (Shuah
     Khan).

   - Add support for per-policy performance boost to cpufreq (Jie Zhan).

   - Fix assorted issues in the cpufreq core, common governor code and
     in the pcc cpufreq driver (Liao Chang)"
