Linux supports this, and if we are to have compatible device tree files,
U-Boot should also.
Avoid giving the device tree files access to U-Boot's include/ directory.
Only include/dt-bindings is accessible.

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

Unlike Linux Kernel, U-Boot historically had *.dts files under
board/$(VENDOR)/dts/ and *.dtsi files under arch/$(ARCH)/dts/.
I think arch/$(ARCH)/dts dicretory is a better location
to store both *.dts and *.dtsi files.
For example, before this commit, board/xilinx/dts directory
had both Microblaze dts (microblaze-generic.dts) and
ARM dts (zynq-*.dts), which are totally unrelated.
This commit moves *.dts to arch/$(ARCH)/dts/ directories,
allowing us to describe nicely mutiple DTBs generation in the next commit.
