Add device tree from Linux for driver model conversion and enable OF_CONTROL. This will remove the following compile warning: ================================================== Device Tree Source is not correctly specified. Please define 'CONFIG_DEFAULT_DEVICE_TREE' or build with 'DEVICE_TREE=<device_tree>' argument =================================================== Target was compile tested, build was clean.
