[RFC PATCH v0 1/5] powerpc/pseries/hotplug-memory: Set DRCONF_MEM_HOTREMOVABLE for hot-plugged mem

[Bharata B Rao]

In addition to setting DRCONF_MEM_HOTREMOVABLE for boot-time hot-plugged
memory, we should set the same too for the memory that gets hot-plugged
post-boot. This ensures that correct LMB flags value is reflected in
ibm,dynamic-memory-vN property.
