after_bootmem has different meaning in 32bit and 64bit.
32bit: after bootmem is ready
64bit: after bootmem is distroyed
Let's merget them make 32bit the same as 64bit.
for 32bit, it is mixing alloc_bootmem_pages, and alloc_low_page under
after_bootmem is set or not set.
alloc_bootmem is just wrapper for memblock for x86.
Now we have alloc_low_page() with memblock too. We can drop bootmem path
now, and only alloc_low_page only.
At the same time, we make alloc_low_page could handle real after_bootmem
for 32bit, because alloc_bootmem_pages could fallback to use slab too.
At last move after_bootmem set position for 32bit the same as 64bit.
