platform-drivers-x86 for v5.19-4

Highlights:
  -  Fix brightness key events getting reported twice on some Dell's
     regression caused by recent Panasonic hotkey fixes
  -  Fix poweroff no longer working on some devices regression caused
     by recent poweroff handler rework
  -  Mark new (in 5.19) Intel IFS driver as broken, because of some issues
     surrounding the userspace (sysfs) API which need to be cleared up
  -  Some hardware-id / quirk additions
 
 The following is an automated git shortlog grouped by driver:
 
 ACPI:
  -  video: Fix acpi_video_handles_brightness_key_presses()
 
 asus-wmi:
  -  Add key mappings
 
 efi:
  -  Fix efi_power_off() not being run before acpi_power_off() when necessary
 
 gigabyte-wmi:
  -  add support for B660I AORUS PRO DDR4
 
 intel_atomisp2_led:
  -  Also turn off the always-on camera LED on the Asus T100TAF
 
 platform/x86/amd/pmc:
  -  Add new platform support
  -  Add new acpi id for PMC controller
 
 platform/x86/intel/ifs:
  -  Mark as BROKEN
 
 x86-android-tablets:
  -  Fix Lenovo Yoga Tablet 2 830/1050 poweroff again
