migration/memory: This patch adds recognition for changes to the associativity of memory blocks described by 'ibm,dynamic-memory-v2'. If the associativity of an LMB has changed, it should be readded to the system in order to update local and general kernel data structures. This patch builds upon previous enhancements that scan the device-tree "ibm,dynamic-memory" properties using the base LMB array, and a copy derived from the updated properties.
