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.
