device-tree: Consolidate device-tree recipe and append
With the introduction of devicetree.bbclass in oe-core/meta, remove the implementation of device tree compilation from device-tree.bb keeping the meta-xilinx specific information and licensing. Also consolidate the device-tree.bb and device-tree.bbappend. The only differences between the existing device-tree.bb implementation and the devicetree.bbclass implementation is the device trees are deployed in a "devicetree/" subdirectory within the deployed images directory.
