Makefile: add rules to generate SPL FIT images
Some platforms require more complex U-Boot images than we can easily generate via the mkimage command line, for instance to load additional image files. Introduce a CONFIG_SPL_FIT_SOURCE and CONFIG_SPL_FIT_GENERATOR symbol, which can either hold an .its source file describing the image layout, or, in the second case, a generator tool (script) to create such a source file. This script gets passed the list of device tree files from the CONFIG_OF_LIST variable. A platform or board can define either of those in their defconfig file to allow an easy building of such an image.
