Now that the Makefile can call a generator script to build a more
advanced FIT image, let's use this feature to address the needs of
Allwinner A64 boards.
The (DTB stripped) U-Boot binary and the ATF are static, but we allow
an arbitrary number of supported device trees to be passed.
The script enters both a DT entry in the /images node and the respective
subnode in /configurations to support all listed DTBs.
This requires to copy the ARM Trusted Firmware build (bl31.bin) into
the U-Boot source directory (or to create a symlink to it).
