DynamicTablesPkg: IORT generator updates for Rev E.d spec
Bugzilla: 3458 - Add support IORT Rev E.d specification updates (https://bugzilla.tianocore.org/show_bug.cgi?id=3458) The IO Remapping Table, Platform Design Document, Revision E.d, Feb 2022 (https://developer.arm.com/documentation/den0049/) introduces the following updates, collectively including the updates and errata fixes to Rev E, Rev E.a, Rev E.b, Rev E.c: - increments the IORT table revision to 5. - updates the node definition to add an 'Identifier' field. - adds definition of node type 6 - Reserved Memory Range node. - adds definition for Memory Range Descriptors. - adds flag to indicate PRI support for root complexes. - adds flag to indicate if the root complex supports forwarding of PASID information on translated transactions to the SMMU. - adds flag to indicate if the root complex supports PASID. - adds flags to define access privilege and attributes for the memory ranges. Therefore, update the IORT generator to: - increment IORT table revision count to 5. - populate Identifier filed if revision is greater than 4. - add support to populate Reserved Memory Range nodes and the Memory range descriptors. - add validation to check that the Identifier field is unique. - Populate the PASID capabilities and Flags field of the Root complex node. - Added checks to not generate IORT Rev E, Rev E.<a,b,c>.
