ARM IORT specification (rev. C) has added two new fields to define
proximity domain for the SMMUv3 node in the IORT table.
Proximity Domain Valid:
Set to 1 if the value provided in the Proximity Domain field is
valid. Set to 0 otherwise.
Proximity domain:
If the Proximity Domain Valid flag is set to 1, this entry
provides the proximity domain to which this SMMU
instance belongs.
Update header file to reflect this.
