- Get Xen Acpi tables from the RSDP structure. And installs Xen ACPI tables
- into the RSDT/XSDT using InstallAcpiTable. Some signature of the installed

- @return EFI_SUCCESS The table was successfully inserted.
- @return EFI_INVALID_PARAMETER Either AcpiTableBuffer is NULL, TableHandle is
- NULL, or AcpiTableBufferSize and the size
- field embedded in the ACPI table pointed to
- by AcpiTableBuffer are not in sync.
