    kboot: Add powerpc stub for enumerate_memory_arch()
    
    Add stub for new MI interface for enumerating memory. Right now powerpc
    looks in the FDT table at a later point in boot since we don't need to
    pass a specific memory table to the kernel. Leave it like that for now,
    but note plans for the future.
