[FFe] update dtc to newer version

This is a FFe request for the new upstream version of device-tree-compiler, 1.2.0, which introduces new features such as include files support.

This tool is primarily of use to developers, but it is also a build-dependency of certain kernel-related packages for powerpc (the various armel kernel packages also have this as a [powerpc] build-dep):

-- natty/main build deps on device-tree-compiler:
linux
linux-ti-omap4
ps3-kboot
qemu-kvm
-- natty/universe build deps on device-tree-compiler:
linux-linaro-mx51
linux-linaro-omap
linux-linaro-s5pv310
linux-linaro-u8500
linux-linaro-vexpress
linux-n900

The debdiff is pretty reasonable.
