[PATCH v1 13/19] ACPICA: Apply ACPI_NONSTRING

["Rafael J. Wysocki" <rjw@rjwysocki.net>]

From: Kees Cook <kees@kernel.org>

ACPICA commit ed68cb8e082e3bfbba02814af4fd5a61247f491b

Add ACPI_NONSTRING annotations for places found that are using char
arrays without a terminating NUL character. These were found during
Linux kernel builds and after looking for instances of arrays of size
ACPI_NAMESEG_SIZE.
