Merge branches 'pm-cpuidle', 'pm-cpufreq' and 'pm-sleep'

Browse source 
* pm-cpuidle:
  intel_idle: stop exposing platform acronyms in sysfs
  cpuidle: menu: Avoid taking spinlock for accessing QoS values

* pm-cpufreq:
  cpufreq: intel_pstate: Fix limits issue with operation mode switching
  cpufreq: qoriq: clean up unused code

* pm-sleep:
  PM / hibernate: Define pr_fmt() and use pr_*() instead of printk()
  PM / hibernate: Untangle power_down()
