Unfortunately this causes some issues for the split device tree repository[0], since things get moved around there. In that context the new .dts ends up at src/arm64/arm/vexpress-v2f-1xv7-ca53x2.dts while the include is at src/arm/vexpress-v2m-rs1.dtsi. The sharing of the .dtsi is legitimate since the baseboard is the same for various vexpress systems whatever processor they use. Rather than using ../../ tricks to pickup .dtsi files from another arch this patch creates a new directory include/dt-bindings/dtsi as a home for such cross-arch .dtsi files, arranges for it to be in the include path when the .dts files are processed by cpp and switches the .dts files to use cpp #include instead of /include/.
