[U-Boot] [PATCH v2 9/9] rockchip: rk3399: Create single image using BINMAN

RK3399 platform has two stage boot loaders like SPL and
U-Boot proper. For each stage we need to burn the image
on to flash with respective offsets.
This patch create a single image using binman, so that
user can get rid of burning different stage boot images.
without this patch:
------------------
₹ sudo dd if=spl/u-boot-spl-rockchip.bin of=/dev/sdc seek=64
₹ sudo dd if=u-boot.itb of=/dev/sdc seek=16384
with this patch:
---------------
₹ sudo dd if=u-boot-rockchip-with-spl.bin of=/dev/sdc seek=64
This would easily extend if other rockchip family SoC's would
make use of single image creation.
