Merge branch 'acpica'

Merge ACPICA material for v6.10.  This is mostly new material included
in the 20240322 upstream ACPICA release.

 - Disable -Wstringop-truncation for some ACPICA code in the kernel to
   avoid a compiler warning  that is not very useful (Arnd Bergmann).

 - Add EINJ CXL error types to actbl1.h (Ben Cheatham).

 - Add support for RAS2 table to ACPICA (Shiju Jose).

 - Fix various spelling mistakes in text files and code comments in
   ACPICA (Colin Ian King).

 - Fix spelling and typos in ACPICA (Saket Dumbre).

 - Modify ACPI_OBJECT_COMMON_HEADER (lijun).

 - Add RISC-V RINTC affinity structure support to ACPICA (Haibo Xu).

 - Fix CXL 3.0 structure (RDPAS) in the CEDT table (Hojin Nam).

 - Add missin increment of registered GPE count to ACPICA (Daniil
   Tatianin).

 - Mark new ACPICA release 20240322 (Saket Dumbre).

 - Add support for the AEST V2 table to ACPICA (Ruidong Tian).
