migration/memory: This patch adds recognition for changes to the associativity of memory blocks described by 'ibm,dynamic-memory-v2' in order to update local and general kernel data structures to reflect those changes. This patch builds upon previous enhancements that scan the device-tree properties to build an LMB array in memory to reuse and evaluate that structure for the new property.
