[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.
