[PATCH 3/3] migration/memory: Support 'ibm,dynamic-memory-v2'

[Michael Bringmann <mwb@linux.vnet.ibm.com>]

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.
