board: add support for chiliBoard
Board support package includes:
* Buildroot defconfig
* Mainline Linux kernel v4.9.6
* Mainline U-Boot (current HEAD revision is used, as board support
patches are not in stable release yet)
* genimage config to create sdcard image
* Board readme.txt
[Peter: use http:// instead of git:// for u-boot]
