The need here is to allow access to headers in arch/$(hdr-arch)/boot/dts, but passing the directory above that allows including files as <dts/foo.h> which is nice. That's the rationale for this patch. But as I mentioned in other threads, I wonder if we should put the header files in arch/$(hdr-arch)/boot/dts at all; Documentation/devicetree/bindings/... would keep the headers adjacent to the documentation for the bindings themselves, and the headers really are part of the binding definitions... That would avoid the issue Michal pointed out, and I think clean up the dtc+cpp include path usage too.

With a new feature dtc+cpp, DT can introduces some definitions in its header files for their own. Some of those DT info can be used in kernel source as well, instead of having the duplicate info in kernel headers. This patch allows kernel source to include those DT headers.
