memblock: replace __alloc_bootmem with memblock_alloc_from

The functions are equivalent, just the later does not require nobootmem
translation layer.

The conversion is done using the following semantic patch:

@@
expression size, align, goal;
@@
- __alloc_bootmem(size, align, goal)
+ memblock_alloc_from(size, align, goal)
