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.
