bootmem: Move contig_page_data definition to bootmem.c/nobootmem.c
Now that bootmem.c and nobootmem.c are separate, it's cleaner to define contig_page_data in each file than in page_alloc.c with #ifdef. Move it. This patch doesn't introduce any behavior change. -v2: According to Andrew, fixed the struct layout. -tj: Updated commit description.
