Subject: [PATCH] arch/arm/mm/init.c: use memblock apis for early memory
 allocations

Switch to memblock interfaces for early memory allocator instead of
bootmem allocator.  No functional change in beahvior than what it is in
current code from bootmem users points of view.

Archs already converted to NO_BOOTMEM now directly use memblock interfaces
instead of bootmem wrappers build on top of memblock.  And the archs which
still uses bootmem, these new apis just fallback to exiting bootmem APIs.
