[U-Boot] [RFC PATCH 10/11] sunxi: Pine64: add FIT image source

[Andre Przywara]

The Pine64 boards require an ARM Trusted Firmware (ATF) image to be
loaded and executes prior to the actual U-Boot proper.
Add a FIT image source file to describe the binaries, also add the
supported DTs to be able to boot multiple boards with one image. Use:
$ tools/mkimage -f boards/sunxi/pine64_atf.its -E pine64_image.itb
to create the image file. Copy (or symlink) the bl31.bin file from
the ARM Trusted Firmware build into the current directory.
