[Buildroot] [PATCH v1 1/1] package/bootgen: add bootgen host package

[Neal Frager]

This patch adds Xilinx bootgen as a host package to buildroot.
bootgen is a required utility for generating a boot.bin for
Xilinx versal products.

In addition, for developers who wish to use secure boot with
Xilinx SoC products such as zynq and zynqmp, bootgen has a
more complete offering in secure boot features than the u-boot
mkimage utility.
