Merge branch 'pm-pci'

Merge PCI device power management updates for 5.16-rc1:

 - Make the association of ACPI device objects with PCI devices more
   straightforward and simplify the code doing that for all devices
   in general (Rafael Wysocki).

 - Eliminate struct pci_platform_pm_ops and handle the both of its
   users (PCI and Intel MID) directly in the PCI bus code (Rafael
   Wysocki).

 - Simplify and clarify ACPI PCI device PM helpers (Rafael Wysocki).

 - Fix ordering of operations in pci_back_from_sleep() (Rafael
   Wysocki).

* pm-pci:
  PCI: PM: Fix ordering of operations in pci_back_from_sleep()
  PCI: PM: Do not call platform_pci_power_manageable() unnecessarily
  PCI: PM: Make pci_choose_state() call pci_target_state()
  PCI: PM: Rearrange pci_target_state()
  PCI: PM: Simplify acpi_pci_power_manageable()
  PCI: PM: Drop struct pci_platform_pm_ops
  PCI: ACPI: PM: Do not use pci_platform_pm_ops for ACPI
  PCI: PM: Do not use pci_platform_pm_ops for Intel MID PM
  ACPI: glue: Look for ACPI bus type only if ACPI companion is not known
  ACPI: glue: Drop cleanup callback from struct acpi_bus_type
  PCI: ACPI: Drop acpi_pci_bus
