From: Bharata B Rao <bhar...@linux.vnet.ibm.com>
ibm,lrdr-capacity has a field to describe the maximum address in bytes
and therefore, the most memory that can be allocated to this guest. We
are using maxmem for this field, but instead should use the actual RAM
address corresponding to the end of hotplug region.
