Move vmalloc_to_page() to mm/vmalloc.
We already have page table manipulation for vmalloc in vmalloc.c. Move the
vmalloc_to_page() function there as well.
Move the definitions for vmalloc related functions in mm.h to a newly created
section. A better place would be vmalloc.h but mm.h is basic and may depend
on these functions. An alternative would be to include vmalloc.h in mm.h
(like done for vmstat.h).
