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.
