spapr: Add LMB DR connectors

Browse source 
Enable memory hotplug for pseries 2.4 and add LMB DR connectors.
With memory hotplug, enforce RAM size, NUMA node memory size and maxmem
to be a multiple of SPAPR_MEMORY_BLOCK_SIZE (256M) since that's the
granularity in which LMBs are represented and hot-added.

LMB DR connectors will be used by the memory hotplug code.

[since this missed the 2.4 cutoff, changing to only enable for 2.5]
