Subject: memblock: replace __alloc_bootmem_nopanic with memblock_alloc_from_nopanic
When __alloc_bootmem_nopanic() is used with explicit lower limit for the
allocation it attempts to allocate memory at or above that limit and falls
back to allocation with no limit set.
The memblock_alloc_from_nopanic() does exactly the same thing and can be
used as a replacement for __alloc_bootmem_nopanic() is such cases.
