David Hildenbrand (Arm) 738de20c4f mm/sparse: move memory hotplug bits to sparse-vmemmap.c ...

Let's move all memory hoptplug related code to sparse-vmemmap.c.

We only have to expose sparse_index_init().  While at it, drop the
definition of sparse_index_init() for !CONFIG_SPARSEMEM, which is unused,
and place the declaration in internal.h.
