It turns out that this breaks chromebook_link, probably because of the
large number of devices it adds to the tree before relocation.

When you can a chance can you please try to figure out a solution for
this? I think we need to be able to mark certain devices as pre-reloc,
but create devices the whole bus. It wastes time and memory.

I believe this is only needed for the serial port at present. How is
that actually detected? Perhaps we could add it to the device tree or
find another way to mark it as pre-relocation?

Simon
