lopper, python-dtc: add new recipes for device tree tools

This device tree tooling is being added as a prequisite for enabling
qemuboot with the Arm 64-bit version of the Xen hypervisor.

lopper: a tool for performing operations on device tree files.
A new recipe inspired by the original from meta-xilinx-bsp.

python-dtc: a python library for the Device Tree compiler.
This is a prerequisite for lopper. Updated import of recipe from
meta-xilinx-bsp for the latest release, version 1.6.1.
