Because of the following:
- IMAGE_CLASSES[doc] = "A list of classes that all images should
inherit." I'm not sure all images should include wic class. I'll probably
make this inheritance conditional.
- so far IMAGE_CLASSES is used for qemuboot, image_types,
image_types_uboot and testimage,
so the usage is more or less follows the description. wic is out of
that usage scenario, I believe.
- 'inherit image_wic' is more explicit than IMAGE_CLASSES +=
"image_types"\n inherit ${IMAGE_CLASSES}
