'the' has a tendency to double up; squash them back down.

This updates the existing documentation to reflect recent updates to
the hotplug event structure, which are in draft form but slated
for inclusion in PAPR/LoPAPR.

Parse ibm,architecture.vec table obtained from the guest and enable
memory node configuration via ibm,dynamic-reconfiguration-memory if guest
supports it. This is in preparation to support memory hotplug for
sPAPR guests.
This changes the way memory node configuration is done. Currently all
memory nodes are built upfront. But after this patch, only memory@0 node
for RMA is built upfront. Guest kernel boots with just that and rest of
the memory nodes (via memory@XXX or ibm,dynamic-reconfiguration-memory)
are built when guest does ibm,client-architecture-support call.
Note: This patch needs a SLOF enhancement which is already part of
SLOF binary in QEMU.

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.
