ACPICA: actbl2: Replace 1-element arrays with flexible arrays
ACPICA commit 44f1af0664599e87bebc3a1260692baa27b2f264
Similar to "Replace one-element array with flexible-array", replace the
1-element array with a proper flexible array member as defined by C99.
This allows the code to operate without tripping compile-time and run-
time bounds checkers (e.g. via __builtin_object_size(), -fsanitize=bounds,
and/or -fstrict-flex-arrays=3).
The sizeof() uses with struct acpi_nfit_flush_address and struct
acpi_nfit_smbios have been adjusted to drop the open-coded subtraction
of the trailing single element. The result is no binary differences in
.text nor .data sections.
