[PATCH v2 2/3] mksunxi_fit_atf.sh: Update FIT component descriptions

Since commit d879616e9e64 ("spl: fit: simplify logic for FDT loading for
non-OS boots"), the SPL looks at the "os" properties of FIT images to
determine where to append the FDT.

The "os" property of the "firmware" image also determines how to execute
the next stage of the boot process, as in 1d3790905d9c ("spl: atf:
introduce spl_invoke_atf and make bl31_entry private").

To support this additional functionality, and to properly model the boot
process, where ATF runs before U-Boot, add the "os" properties and swap
the firmware/loadable images in the FIT image.
