Merge branches 'pm-sleep', 'pm-domains' and 'pm-avs' 

* pm-sleep:
  PM / suspend: make sync() on suspend-to-RAM build-time optional
  PM / sleep: Allow devices without runtime PM to do direct-complete
  PM / autosleep: Use workqueue for user space wakeup sources garbage collector

* pm-domains:
  PM / Domains: Fix typo in description of genpd_dev_pm_detach()
  PM / Domains: Remove unusable governor dummies
  PM / Domains: Make pm_genpd_init() available to modules
  PM / domains: Align column headers and data in pm_genpd_summary output
  PM / Domains: Return -EPROBE_DEFER if we fail to init or turn-on domain
  PM / Domains: Correct unit address in power-controller example
  PM / Domains: Remove intermediate states from the power off sequence

* pm-avs:
  PM / AVS: rockchip-io: add io selectors and supplies for rk3368
  PM / AVS: rockchip-io: depend on CONFIG_POWER_AVS
