tools: add cbootimage for tegra

Tegra BCT and bootable flash image generator/compiler

>From documentation:
This project provides a tool which compiles BCT (Boot Configuration
Table) images to place into the boot flash of a Tegra-based device.

The tool will either:

a) Compile a textual representation of a BCT into a binary image.

b) Generate an entire boot image from a previously compiled BCT and a
   bootloader binary.
