kernel: Pull uImage generation into separate class
Pull the uImage image format generation from kernel.bbclass into a separate kernel-uimage.bbclass. Introduce new KERNEL_CLASSES variable, which allows registration of additional classes which implement new kernel image types. The default value of is to register kernel-uimage to preserve the original behavior.
