Merge branches 'acpi-video' and 'acpi-processor' into acpi

Merge ACPI backlight driver fixes and an ACPI processor driver fix for
6.7-rc3:

 - Avoid powering up GPUs while attempting to fix up power for their
   children (Hans de Goede).

 - Use raw_safe_halt() instead of safe_halt() in acpi_idle_play_dead()
   so as to avoid triple-falts during CPU online in Xen HVM guests due
   to the setting of the hardirqs_enabled flag in safe_halt() (David
   Woodhouse).

* acpi-video:
  ACPI: video: Use acpi_device_fix_up_power_children()
  ACPI: PM: Add acpi_device_fix_up_power_children() function

* acpi-processor:
  ACPI: processor_idle: use raw_safe_halt() in acpi_idle_play_dead()
