[PATCH 2/2] kbuild: Don't assume dts files live in arch/*/boot/dts

[Masahiro Yamada]

Barebox has not adopted arch/$(SRCARCH)/dts/$(VENDOR)/ directory
to contain device trees yet, but it is possible in the future.
(you can see that in ARM64 Linux)

It is better to use $(dir $<) rather than hardcoding the particular
include path (and this is the way used in Linux).

Refer commit ad06156876c0e55a01e13e1f2dd5c7f9262b1dfa ("kbuild: Don't
assume dts files live in arch/*/boot/dts") of Linux.
