Pull power management fixes from Rafael Wysocki:
 "These fix a PCI power management regression introduced during the 4.17
  cycle and fix up the recently added support for devices in multiple
  power domains.

  Specifics:

   - Resume parallel PCI (non-PCIe) bridges on suspend-to-RAM (ACP S3)
     to avoid confusing the platform firmware which started to happen
     after a core power management regression fix that went in during
     the 4.17 cycle (Rafael Wysocki).

   - Fix up the recently added support for devices in multiple power
     domains by avoiding to power up the entire domain unnecessarily
     when attaching a device to it (Ulf Hansson)"
