migration from ucl2.xml to uuu script

**Most case user can use uboot fastboot protocol to finish image program work.

In case you have to load kernel to burn whole image.

The below simple map ucl2.xml to uuu script.

	<CMD state="BootStrap" type="boot" body="BootStrap" file ="firmware/flash.bin" ifdev="MX8QXPB0">Loading boot image</CMD>
