This allows a generic U-Boot (proper) image to be combined with a bunch

Eventually this string can be written after the build process by some

Allwinner boards with 64-bit SoCs (A64 and H5).
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.
The location of the bl31.bin image from the ARM Trusted Firmware build

Changes in V2:

Split this off from the device sub submissions
In some boards like the Raspberry Pi the initial bootloader will pass
a DT to the kernel. When using U-Boot as such kernel, the board code in
U-Boot should be able to provide U-Boot with this, already assembled
device tree blob.
This patch introduces a new config option CONFIG_OF_BOARD to use instead
of CONFIG_OF_EMBED or CONFIG_OF_SEPARATE which will initialize the DT
from a board-specific funtion instead of bundling one with U-Boot or as
a separated file. This allows boards like the Raspberry Pi to reuse the
device tree passed from the bootcode.bin and start.elf firmware
files, including the run-time selected device tree overlays.
