If we really want to avoid soft links then I did try to add the subree
with the prefix as dts/upstream here [1]. It works well with the
downside that we will pollute the subtree source code with U-Boot
specific Makefiles [2]. However, the subtree pull works fine still. If
this sounds better to you and Simon then let me know I will use this
approach for v4.
