When ACPI_MISALIGNMENT_NOT_SUPPORTED, GCC can produce a bogus -Wstringop-overread warning, see https://gcc.gnu.org/PR122073.
To me it's very clear that we have a compiler bug here, thus just disable the warning.

Please submit ACPICA changes to the upstream ACPICA project on GitHub as pull requests (PRs). After a given PR has been merged upstream, a corresponding Linux patch can be submitted with a Link: tag pointing to the upstream commit, but note that upstream ACPICA material is automatically transferred to Linux, so it should not be necessary to do so unless timing is important.
The Link: tag is above. The issue here is this bug is preventing automatic test of arch/loongarch (see another Link: tag).
