Merge branch 'acpica'

Merge ACPICA updates for 5.16-rc1:

 - Fix system-wide resume issue caused by evaluating control methods
   too early in the resume path (Rafael Wysocki).

 - Add support for Windows 2020 _OSI string (Mario Limonciello).

 - Add Generic Port Affinity type for SRAT (Alison Schofield).

 - Add disassembly support for the NHLT ACPI table (Bob Moore).

* acpica:
  ACPICA: Update version to 20210930
  ACPICA: iASL table disassembler: Added disassembly support for the NHLT ACPI table
  ACPICA: ACPI 6.4 SRAT: add Generic Port Affinity type
  ACPICA: Add support for Windows 2020 _OSI string
  ACPICA: Avoid evaluating methods too early during system resume
