[PATCH -v2] x86: Fix section mismatch with memblock_find_region()
Stephen found
WARNING: mm/built-in.o(.text+0x25ab8): Section mismatch in reference from the function memblock_find_base() to the function .init.text:memblock_find_region()
The function memblock_find_base() references
the function __init memblock_find_region().
This is often because memblock_find_base lacks a __init
annotation or the annotation of memblock_find_region is wrong.
So let memblock_find_region() to use __init_memblock insteaf of __init directly.
Also make left function that doesn't have __init* to carry __init_memblock.
