ACPICA: Disassembler: Add support for the ToUUID opererator (macro).
This change adds support to disassemble a UUID back to the original ToUUID operator. It will detect a UUID within a standard AML Buffer. Also, a description of the UUID is emitted for "known" UUIDs, defined as UUIDs that are defined in the ACPI specification. Since this is a change for disassembler which is not shipped in the Linux kernel, the Linux kernel is not affected.
