ACPICA: ACPI 6.4: add SDEV secure access components
ACPICA commit 44ca5f4f9be24bf64524cdb1de46322509319056 This entails adding an optional subtable indicating secure access components as well as two different types of secure access components (ID-based or Memory). For definitons and uses, consult the ACPI specification.
