memblock: replace alloc_bootmem_low_pages with memblock_alloc_low

The alloc_bootmem_low_pages() function allocates PAGE_SIZE aligned regions
from low memory. memblock_alloc_low() with alignment set to PAGE_SIZE does
exactly the same thing.

The conversion is done using the following semantic patch:

@@
expression e;
@@
- alloc_bootmem_low_pages(e)
+ memblock_alloc_low(e, PAGE_SIZE)
