This adds the devicetree compiler (dtc) and rules to generate dtbs
to barebox. With this devicetrees can be compiled into the barebox
binary and devices can be probed from it. Also added are i.MX27
devicetree files, these are basically meant as example, I won't apply
them eight now.

The dtc probably doesn't make it to the list due to its size. This
doesn't really matter, it's the unchanged version from the kernel.

Also in this series, currently not for merging are some basic i.MX27
devicetree files.

This all works quite good, but there is a problem. Devices in barebox
are usually registered in various initcalls. Most drivers currently
unfortunately don't test if dev_request_mem_region succeeds, instead
they silently try to access NULL pointers. So if you test this series,
make sure that no devices are registered twice.
