mm/mm_init.c: add new function calc_nr_all_pages()
This is a preparation to calculate nr_kernel_pages and nr_all_pages, both
of which will be used later in alloc_large_system_hash().
nr_all_pages counts up all free but not reserved memory in memblock
allocator, including HIGHMEM memory. While nr_kernel_pages counts up all
free but not reserved low memory in memblock allocator, excluding HIGHMEM
memory.
