mm: prepare to move subsection_map_init() to mm/sparse-vmemmap.c
We want to move subsection_map_init() to mm/sparse-vmemmap.c.
To prepare for getting rid of subsection_map_init() in mm/sparse.c
completely, use a static inline function for !CONFIG_SPARSEMEM_VMEMMAP.
While at it, move the declaration to internal.h and rename it to
"sparse_init_subsection_map()".
