These parsing functions are APCI DMAR table specific and are used only
by intel-iommu routines. Because of this I didn't change their names but
just moved to intel-iommu.c to cleanup some of the ifdef's in the common
dmar.c code (specific to handling common ACPI DMAR tables etc) shared by
both DMA-remapping (iommu) and IRQ-remapping.
