The difficulty with that is that to support KVM we need
to let KVM (ie the CPU object) override the board's ideas
about mpidr, because the kernel doesn't yet support letting
the board model inform it about what mpidr values to use.
So we probably need to have 'board model sets cpu property,
everything else reads cpu property which might or might not
be what the board hoped for'.
