I've tried to abstract the user visible parts outside any particular
firmware implementation, but HMAT parsing is an ACPI specific feature,
so I thought ACPI was a good home for this part. I'm open to suggestions
if there's a better place. Either under in another existing subsystem,
or create a new one under drivers/hmat/?
