SGI IP27 got its own code to set the early memory allocator up since it's
NUMA-based system. So in order to be compatible with NO_BOOTMEM config
we need to discard the bootmem allocator initialization and insert the
memblock reservation method. Although in my opinion the code isn't
working anyway since I couldn't find a place where prom_meminit() called
and kernel memory isn't reserved. It must have been untested since the
time the arch/mips/mips-boards/generic code was in the kernel.
