Merge branch 'pm-assorted'

* pm-assorted:
  suspend: enable freeze timeout configuration through sys
  ACPI: enable ACPI SCI during suspend
  PM: Introduce suspend state PM_SUSPEND_FREEZE
  PM / Runtime: Add new helper function: pm_runtime_active()
  PM / tracing: remove deprecated power trace API
  PM: don't use [delayed_]work_pending()
  PM / Domains: don't use [delayed_]work_pending()
