ACPI: Add RHSA and ANDD structures for DMAR table
Remapping Hardware Status Affinity (RHSA) structure is applicable for
platforms supporting non-uniform memory. An ACPI Name-space Device
Declaration (ANDD) structure uniquely represents an ACPI name-space
enumerated device capable of issuing DMA requests in the platform.
Add RHSA and ANDD structures support for DMAR table generation.
