Merge ACPI backlight driver updates, ACPI APEI updates, ACPI PRM updates
and changes related to ACPI PCC for 6.7-rc1:

 - Add acpi_backlight=vendor quirk for Toshiba Portégé R100 (Ondrej
   Zary).

 - Add "vendor" backlight quirks for 3 Lenovo x86 Android tablets (Hans
   de Goede).

 - Move Xiaomi Mi Pad 2 backlight quirk to its own section (Hans de
   Goede).

 - Annotate struct prm_module_info with __counted_by (Kees Cook).

 - Fix AER info corruption in aer_recover_queue() when error status data
   has multiple sections (Shiju Jose).

 - Make APEI use ERST max execution time value for slow devices (Jeshua
   Smith).

 - Add support for platform notification handling to the PCC mailbox
   driver and modify it to support shared interrupts for multiple
   subspaces (Huisong Li).

 - Define common macros to use when referring to various bitfields in the
   PCC generic communications channel command and status fields and use
   them in some drivers (Sudeep Holla).
