memory hotplug/s390: set phys_device

Implement arch specific arch_get_memory_phys_device function and
initialize phys_device for each memory section.  That way we finally can
tell which piece of memory belongs to which physical device.

This makes s390's /sys/devices/system/memory/memoryX/phys_device display
the correct thing?
