spapr: Support ibm, lrdr-capacity device tree property

Browse source 
Add support for ibm,lrdr-capacity since this is needed by the guest
kernel to know about the possible hot-pluggable CPUs and Memory. With
this, pseries kernels will start reporting correct maxcpus in
/sys/devices/system/cpu/possible.

Also define the minimum hotpluggable memory size as 256MB.
