ACPICA: Apply ACPI_NONSTRING 

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.
