    [POWERPC] Small cleanups to the cuboot bootwrapper code
    
    This patch makes a few small cleanups to the cuboot code.
        - It removes the double layered selection of images, via
    cuboot-plat-y, instead having the cuboot platforms directly select a
    suitable image-y (this changes the name of the final cuboot image from
    plain cuImage to cuImage.<platform>).
        - Factors out some code in the wrapper that's potentially
    useful to platforms other than uboot.
