Merge branch 'acpica'

Merge ACPICA changes, including bug fixes and cleanups as well as support
for some recently defined data structures, for 6.2-rc1:

 - Make acpi_ex_load_op() match upstream implementation (Rafael Wysocki).
 - Add support for loong_arch-specific APICs in MADT (Huacai Chen).
 - Add support for fixed PCIe wake event (Huacai Chen).
 - Add EBDA pointer sanity checks (Vit Kabele).
 - Avoid accessing VGA memory when EBDA < 1KiB (Vit Kabele).
 - Add CCEL table support to both compiler/disassembler (Kuppuswamy
   Sathyanarayanan).
 - Add a couple of new UUIDs to the known UUID list (Bob Moore).
 - Add support for FFH Opregion special context data (Sudeep Holla).
 - Improve warning message for "invalid ACPI name" (Bob Moore).
 - Add support for CXL 3.0 structures (CXIMS & RDPAS) in the CEDT table
   (Alison Schofield).
 - Prepare IORT support for revision E.e (Robin Murphy).
 - Finish support for the CDAT table (Bob Moore).
 - Fix error code path in acpi_ds_call_control_method() (Rafael Wysocki).
 - Fix use-after-free in acpi_ut_copy_ipackage_to_ipackage() (Li Zetao).
 - Update the version of the ACPICA code in the kernel (Bob Moore).
