[Buildroot] [PATCH v3 1/2] host-zynq-boot-bin: new package

[Jan Viktorin <xvikto03@stud.fit.vutbr.cz>]

From: Jan Viktorin <viktorin@rehivetech.com>

The package creates file images/boot.bin to boot
Xilinx Zynq based boards. It might not work with
U-Boot older then 2015.07.

The script zynq-boot-bin.py is contained in the
Xilinx repository of U-Boot (it is not in upstream).

Signed-off-by: Jan Viktorin <viktorin@rehivetech.com>

Changes:
 * v0->v1: create this package instead of patching U-Boot by zynq-boot-bin.py
 * v1->v2: call zynq-boot-bin.py from the package
 * v2->v3: remove python deps, do not download U-Boot, just the script
