If the HMAT Subsystem Address Range provides a valid processor proximity domain for a memory domain, or a processor domain matches the performance access of the valid processor proximity domain, register the memory target with that initiator so this relationship will be visible under the node's sysfs directory. Since HMAT requires valid address ranges have an equivalent SRAT entry, verify each memory target satisfies this requirement.
