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.

This v6 series:
* Updates teh IORT header to add definition for IORT Rev 4
and RMR Node 2 so that appropriate checks can be performed
for deprecated table/node revisions.
* Adds checks to not generate IORT table Rev E, E.<a,b,c>.
* Addresses the feedback received for Acpiview to:
- Make output format for Flags filed consistent.
- Define macro for IORT Rev E.c and RMR Node revision 2
and use these to check for deprecated table/node
revisions.
- Added check to skip parsing if IORT Rev E, E.<a,b,c>
as various fields were deprecated between revisions.

The v5 series:
* Addresses the feedback for IORT Revision macro.
* Reorders the patches in the series and updates
"MdePkg: IORT header update for IORT Rev E.d spec"
patch to include changes for IORT generator to prevent
git bisect from breaking.

The v4 series:
* Updates the IORT header to reflect Rev E.d:
- Add flag to indicate if the root complex supports PASID.
- Add flags to define access privilege and attributes for the
memory ranges.
* Adds validations to Acpiview to:
- Check that the IORT Table Revision is not 4 as IORT
Rev E.c is deprecated.
- Check that the IORT RMR node revision is not 2 as it
breaks backward compatibility and was deprecated as
part of IORT Rev E.c.
* Updates Dynamic Tables Framework to support generation of
IORT revision E.d.

The v3 series:
- Dropped [PATCH v2 1/8] MdePkg: Fix IORT header file include
guard as suggested at
https://edk2.groups.io/g/devel/message/76656
- Removed definition of EFI_ACPI_IO_REMAPPING_TABLE_REVISION as
EFI_ACPI_IO_REMAPPING_TABLE_REV0 has been provided for
representing Rev 0.
- Moved error handling code for IdMappingToken from patch v2 6/8
and v2 8/8 into a separate patch.
- Moved Identifier field before Flags field in CM_ARM_RMR_NODE.
- Added description for CM_ARM_MEMORY_RANGE_DESCRIPTOR field.

The v2 patch series includes all changes from v1 patch series
except the following 2 patches have been modified to set the
EFI_ACPI_IO_REMAPPING_TABLE_REVISION macro to Rev 0 as setting
to Rev 3 will break existing platforms, the problem being that
the Identifier field in the IORT nodes would not be unique.
- MdePkg: IORT header update for IORT Rev E.b spec
- DynamicTablesPkg: IORT generator updates for Rev E.b spec

The v1 patch series:
- Updates the IORT header file to match the Rev E.b specification.
- Add support to parse IORT Rev E.b tables
- Add support to generate IORT Rev E.b compliant ACPI tables
using Dynamic Tables Framework.
