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.
