acpi: add DMAR scope definition for root IOAPIC
To enable interrupt remapping for intel IOMMU device, each IOAPIC device
in the system reported via ACPI MADT must be explicitly enumerated under
one specific remapping hardware unit. This patch adds the root-complex
IOAPIC into the default DMAR device.
Please refer to VT-d spec 8.3.1.1 for more information.
