    powerpc/boot: Allocate more memory for dtb
    
    David Gibson suggested that since we are now unconditionally copying
    the dtb into a malloc()ed buffer, it would be sensible to add a little
    padding to the buffer at that point, so that further device tree
    manipulations won't need to reallocate it.
    
    This implements that suggestion.
