vimc: Virtual Media Control VPU's

* This patch series add to the vimc driver video processing units ad a debayer and a scaler.
* The test pattern generator from vivid driver was exported as a module, as it is used by the vimc driver as well.
* The debayer transforms the bayer format image received in its sink pad to a bayer format by avaraging the pixels within a mean window
* The scaler only scales up the image for now.
* The ioctls to configure the format in the pads were implemented to allow testing the pipe from the user space

The patch series is based on 'vimc/review/video-pipe' branch, it goes on top of the patch named "[media] vimc: Virtual Media Controller core, capture and sensor" and is available at
