Subject: [PATCH] arc: Add "include chroot" for DT bindings

Basically this extends
c58299aa8754 "kbuild: create an "include chroot" for DT bindings" for
ARC where we extensively use Device Tree and there're good reasons
to use DT bindings, especially if those are required.

Otherwise on attempt to compile .dts with something like:
-------------------->8---------------------
 #include <dt-bindings/net/ti-dp83867.h>
-------------------->8---------------------

we inevitably see this compilation failure:
-------------------->8---------------------
arch/arc/boot/dts/hsdk.dts:16:40: fatal error: dt-bindings/net/ti-dp83867.h: No such file or directory
 #include <dt-bindings/net/ti-dp83867.h>
                                        ^
compilation terminated.
-------------------->8---------------------
