ACPI: Add code to create root port entry in DMAR table

Hardware / Coreboot - Werner Zeh [siemens.com] - 2 August 2016 23:24 UTC

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".
