The ibm,dynamic-reconfiguration-memory/ibm,associativity-lookup-arrays
property used to track the associativity for LMBs assigned to a system
may not contain all of the possible associativity arrays for the system
at boot time. When a LMB is added to the system and its associativity
array is not present in the lookup array we need to update the lookup
array to contain the new associativity array.

The first patch splits the code that creates a clone of a property into
its own routine so this can be used for cloning any of the properties
used during memory hotplug.

The second patch updates the associativity lookup code to dynamically
add new associativity arrays to the lookup array if they are not
