Aaron Durbin d4afa938c3 lib/bootmem: allow architecture specific bootmem ranges
A architecture-specific function, named bootmem_arch_add_ranges(),
is added so that each architecture can add entries into the bootmem
memory map. This allows for a common write_tables() implementation
to avoid code duplication.
