Merge branches 'pm-cpufreq' and 'pm-runtime'

Merge cpufreq fixes and fixes related to runtime PM for 7.4-rc3:

 - Fix the synchronization of boost state updates in cpufreq (Christian
   Loehle)

 - Fix issues related to system suspend-resume synchronization in the
   cpufreq core and intel_pstate driver (Rafael Wysocki)

 - Fix P-state index mismatch in extract_io() in the ACPI cpufreq driver
   on systems with defective _PSS (Li RongQing)

 - Fix issues related to target frequency caching in cpufreq (Rafael
   Wysocki)

 - Prevent a false-positive warning in pm_runtime_remove() introduced
   by a previous fix during the 7.0 development cycle (Zhou Minqiang)

 - Extend a recent improvement related to the handling of suppliers
   during device runtime-suspend to some previously missed cases in
   which it is relevant for consistency (Brian Norris)

 - Update runtime PM documentation to reflect new behavior after recent
   changes (Stanley Jhu)

 - Add last_busy timestamp updates for devices requested to resume from
   runtime suspend that are missing if those devices are not actually
   suspended (Rafael Wysocki)
