This updates the device tree manipulation routines so that memory add/remove of lmbs represented under the ibm,dynamic-reconfiguration-memory node of the device tree invokes the hotplug notifier chain. This change is needed because of the change in the way memory is represented under the ibm,dynamic-reconfiguration-memory node. All lmbs are described in the ibm,dynamic-memory property instead of having a separate node for each lmb as in previous device tree layouts. This requires the update_node() routine to check for updates to the ibm,dynamic-memory property and invoke the hotplug notifier chain. This also updates the pseries hotplug notifier to be able to gather information for lmbs represented under the ibm,dynamic-reconfiguration-memory node and have the lmbs added/removed.
