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.
