The Device Tree is commonly used but it is still kept as a .inc file instead of a proper class. Instead now we move the Device Tree code to a kernel-devicetree class and automatically enable it when the KERNEL_DEVICETREE variable is set. To avoid breakage in existing layers, we kept a linux-dtb.inc file which raises a warning telling the user about the change so in next release this can be removed.
