It probably would be handier to have the dtb there but its a source
tree, so let's keep source there.

It'll just be a fact of life for a non-devtree fw platform user that
they need to find and use dtc and an attach tool to stick the dtb
onto the zImage.

I don't think anyone was actually serious about including dtc in the kernel.
