[media] Add the via framebuffer camera controller driver
Add a driver for the video capture port on VIA integrated chipsets. This
version has a remaining OLPCism or two and expects to be talking to an
ov7670; those can be improved as the need arises.
This work was supported by the One Laptop Per Child project.
Thanks to Laurent Pinchart for a number of useful comments.
