The root node path must be internally converted to "/", or various
pieces of code looking for it that way will fail. The code to do
that however had a bug where we might incorrectly append pieces
of the original path from the fdt to the "/".
We should probably add a proper dedicated accessor for the root node
but in the meantime this patch should fix it.
