Subject[PATCH: 011/012] Memory hotplug for new nodes v.2 (Register start func for acpi_memhotplug)

This is a patch to create start function which calls add_memory().
Container driver can call add_memory() by this. If this is not,
even if the node which is defined container device in DSDT is added,
the container driver can't call memory hotplug code.
