Merge branches 'acpi-scan', 'acpi-pm', 'acpi-power' and 'acpi-pci' 

Merge ACPI device enumeration updates, ACPI power management updates
and PCI host bridge ACPI driver updates for 5.17-rc1:

 - Introduce acpi_fetch_acpi_dev() as a replacement for
   acpi_bus_get_device() and use it in the ACPI subsystem (Rafael
   Wysocki).

 - Avoid using _CID for device enumaration if _HID is missing or
   invalid (Rafael Wysocki).

 - Rework quirk handling during ACPI device enumeration and add some
   new quirks for known broken platforms (Hans de Goede).

 - Avoid unnecessary or redundant CPU cache flushing during system
   PM transitions (Kirill A. Shutemov).

 - Add PM debug messages related to power resources (Rafael Wysocki).

 - Fix kernel-doc comment in the PCI host bridge ACPI driver (Yang Li).

* acpi-scan:
  serdev: Do not instantiate serdevs on boards with known bogus DSDT entries
  i2c: acpi: Do not instantiate I2C-clients on boards with known bogus DSDT entries
  ACPI / x86: Add acpi_quirk_skip_[i2c_client|serdev]_enumeration() helpers
  ACPI: scan: Create platform device for BCM4752 and LNV4752 ACPI nodes
  ACPI: Use acpi_fetch_acpi_dev() instead of acpi_bus_get_device()
  ACPI: scan: Introduce acpi_fetch_acpi_dev()
  ACPI: scan: Do not add device IDs from _CID if _HID is not valid

* acpi-pm:
  ACPI: PM: Remove redundant cache flushing
  ACPI: PM: Avoid CPU cache flush when entering S4

* acpi-power:
  ACPI: PM: Emit debug messages when enabling/disabling wakeup power

* acpi-pci:
  PCI/ACPI: Fix acpi_pci_osc_control_set() kernel-doc comment
