Support for device-tree appended to zImage

The following series support for device tree binary blobs (dtb) that are appended to the compressed kernel image (zImage).

Having appended dtb data is not required to boot with a device tree. If no dtb data is appended to zImage, the kernel will boot using prior methods.
