    ACPI: Add code to create root port entry in DMAR table
    
    PCI root ports with "Address Translation Service" capability can be
    reported in DMAR table in the ATSR scope to let the OS know how to
    handle these devices the right way when VT-d is used.
    Add code to create an entry for a PCI root port using the type
    "SCOPE_PCI_SUB".
