Sami:
I agree this change. With this patch, will you update the existing
platform to use the matched version macro
EFI_ACPI_IO_REMAPPING_TABLE_REV0?
[SAMI] I can update the platforms in edk2-platforms as a follow-on patch. In
that case the macro EFI_ACPI_IO_REMAPPING_TABLE_REVISION can also be
removed.
Please let me know if this approach would be better, and I can send an
update.

Thanks
