Add a script to generate binaries from bl31.elf, and generate u-boot.its file for FIT image including u-boot, dtb and atf binaries.

This doesn't work if the ATF BL31_BASE is 0x1000 instead of 0x10000, but there are other reasons why 0x1000 doesn't work. Tested this with ATF v1.4 with BL31_BASE moved back to 0x10000, and that works fine. So this is defenitely progress! This allows me to build my own firmware for the Firefly-RK3399 with a sane console speed of 115200.
