pipeline: raspberrypi: vc4: Fix configuration of the embedded data node
The Unicam embedded data video device suffers from two issues with the
upstream driver:
- The driver uses the generic metadata V4L2_META_FMT_GENERIC_* formats,
instead of the downstream V4L2_META_FMT_SENSOR_DATA.
- The driver requires the width and height of the embedded data stream
to be configured.
Fix them both.
