Move bootmem info registration common API to individual bootmem_info.c.
And we will use {get,put}_page_bootmem() to initialize the page for the
vmemmap pages or free the vmemmap pages to buddy in the later patch.
So move them out of CONFIG_MEMORY_HOTPLUG_SPARSE. This is just code
movement without any functional change.

Looks like incomplete

Not that my comment was, I should have said

The copyright looks very incomplete

Yes. Just copied from mm/memory_hotplug.c.
I can improve it in the next version. Thanks.
