Pull power management updates from Rafael Wysocki:
"These fix the (Intel-specific) Performance and Energy Bias Hint (EPB)
handling and expose it to user space via sysfs, fix and clean up
several cpufreq drivers, add support for two new chips to the qoriq
cpufreq driver, fix, simplify and clean up the cpufreq core and the
schedutil governor, add support for "CPU" domains to the generic power
domains (genpd) framework and provide low-level PSCI firmware support
for that feature, fix the exynos cpuidle driver and fix a couple of
issues in the devfreq subsystem and clean it up.
