It is convenient to have all device trees on the same SoC compiled. It allows for later easy repackaging without the need to re-run the make file.
- Build device trees with the same SoC under arch/$(ARCH)/dts
- Copy the one specified by CONFIG_DEFAULT_DEVICE_TREE or DEVICE_TREE=... to dts/dt.dtb

This better matches what the kernel does, but I'm not 100% comfortable about putting all these files in arch/arm. Granted the vendor directory may not correspond to a particular SoC, but we can put tegra20.dtsi in arch/arm/dts so that all tegra boards can use it, for example.
