NUMA resource associativity
-=============================

Associativity represents the groupings of the various platform resources into
domains of substantially similar mean performance relative to resources outside

bit 2 of byte 5 in the "ibm,architecture-vec-5" property is used.
Form 0

Form 0 associativity supports only two NUMA distances (LOCAL and REMOTE).

With Form 1 a combination of ibm,associativity-reference-points, and ibm,associativity
device tree properties are used to determine the NUMA distance between resource groups/domains.
