Allow u-boot to build DTB from a different directory tree such that
*-u-boot.dtsi files can be included from a common location. Currently
that location is arch/$(ARCH)/dts/, so statically define that common
location.

This is needed for platform owners to start building DTB files from
devicetree-rebasing directory but still being able to include
*-u-boot.dtsi files.
