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.
