[POWERPC] Hotplug memory remove notifications for powerpc
Hotplug memory remove notifier for 64-bit powerpc. This gets invoked
by writing to /proc/ppc64/ofdt the string "remove_node " followed by
the firmware device tree pathname of the node that needs to be removed.
In response, this adjusts the sections and removes sysfs entries by
calling __remove_pages(). Then it calls arch-specific code to get rid
of the hardware MMU mappings for the section of memory.
