Video support for EfikaSB

[Sascha Hauer]

This series adds video support to the EfikaSB. Several infrastructure
additions are necessary for this. First the of_graph binding is introduced
to barebox which is necessary to describe the topology of the video
hardware in the device tree. With this we can describe the various
video encoders intern and extern to the SoC. Next we introduce the video
pipeline concept (VPL). This makes it possible to chain together the
different video encoders. It's possible to throw an ioctl into one
end of the chain and each encoder is responsible to handle the ioctl
and to pass it on to the next entitity in the chain. Support for the
MTL017 LVDS encoder found in the EfikaSB and support for simple panels
make this series complete.
