migration/memory: This patch adds a new pseries hotplug action for CPU and memory operations, PSERIES_HP_ELOG_ACTION_READD_MULTIPLE. This is a variant of the READD operation which performs the action upon multiple instances of the resource at one time. The operation is to be triggered by device-tree analysis of updates by RTAS events analyzed by 'migation_store' during post-migration processing. It will be used for memory updates, initially.
