From: Swatisri Kantamsetti <swatis...@nvidia.com>
The IO Remapping Table, Platform Design Document, Revision E.e,
Sept 2022 (https://developer.arm.com/documentation/den0049/ee)
added flags in SMMUv3 node for validity of ID mappings for MSIs
related to control interrupts.
Therefore, update the IORT header file to:
- increment IORT table revision to 6
- add support for DeviceId valid flag
