Merge: Update ACPI to match v6.10

MR: https://gitlab.com/redhat/centos-stream/src/kernel/centos-stream-9/-/merge_requests/5014

JIRA: https://issues.redhat.com/browse/RHEL-54149
Omitted-fix: 7cc06e7
Omitted-fix: e075c3b
    both of these fixes to drivers/platform/x86 required multiple additional patches before they would apply semi-cleanly, and I did not want to take the additional commits into an already long series
Omitted-fix: 4ce8f4c
Omitted-fix: d80b83c
        These are both the same commit under two different hashes. They apply to drivers/platform/x86/x86-android-tablets.c, which is not present in centos-9.
Omitted-fix: 0e6b6de
        This commit was reverted two months later by 779bac9. Simplify the history by not including either of them.
