This patch isn't a fix, though, it's merely adding some new stuff from a
new release of the IORT spec.

Either way, since I discovered we do actually have approval to
contribute to ACPICA directly, I now intend to route the header change
that way per Rafaels' preference[1] - patch 2/2 will take care of itself
in the meantime.

Thanks,
Robin.
