mm/nobootmem.c: remove duplicate macro ARCH_LOW_ADDRESS_LIMIT statements
Fix the following bugs:
- the same ARCH_LOW_ADDRESS_LIMIT statements are duplicated between
header and relevant source
- don't ensure ARCH_LOW_ADDRESS_LIMIT perhaps defined by ARCH in
asm/processor.h is preferred over default in linux/bootmem.h
completely since the former header isn't included by the latter
