Makefile: Add target for combined u-boot.img & spl/u-boot.bin
This new make target "u-boot-img-spl-at-end.bin" consists of the the real, full-blown U-Boot image and the U-Boot SPL binary directly attached to it. The full-blown U-Boot image has the mkimage header included, with its load-address and entry-point. This will be used by the upcoming lwmon5 PPC440EPx derivate board port.
