Merge x86-specific ACPI changes, an ACPI backlight driver change, ACPI
APEI change and miscellaneous ACPI-related changes for 6.9-rc1:

 - Add DELL0501 handling to acpi_quirk_skip_serdev_enumeration() and
   make that function generic (Hans de Goede).

 - Make the ACPI backlight code handle fetching EDID that is longer than
   256 bytes (Mario Limonciello).

 - Skip initialization of GHES_ASSIST structures for Machine Check
   Architecture in APEI (Avadhut Naik).

 - Convert several plaform drivers in the ACPI subsystem to using a
   remove callback that returns void (Uwe Kleine-König).

 - Drop the long-deprecated custom_method debugfs interface that is
   problematic from the security standpoint (Rafael Wysocki).

 - Use %pe in a couple of places in the ACPI code for easier error
   decoding (Onkarnath).
