[SBC] Orange Pi Zero

I would like to add support for the Orange Pi Zero, and ideally some of the other Orange Pi's. I am planning to use Orange Pi Zero to run a workshop this year, and would ideally like to use gobot for it.

Some helpful links: Orange Pi Armbian - the best board image for Orange Pi boards

Armbian has an image with a newer kernel (4.x) for the Orange Pi, and I believe that sysfs access to GPIO works. I will check tommorow on one of my Orange Pi One boards.
