The example in video-interfaces.yaml uses a bunch of undocumented
bindings which will cause warnings when undocumented compatible checks
are enabled. The example could be fixed to use documented bindings, but
doing so would just duplicate other examples. So let's just remove the
example.

-  # The example snippet below describes two data pipelines.  ov772x and imx074
-  # are camera sensors with a parallel and serial (MIPI CSI-2) video bus
-  # respectively. Both sensors are on the I2C control bus corresponding to the
-  # i2c0 controller node.  ov772x sensor is linked directly to the ceu0 video
-  # host interface. imx074 is linked to ceu0 through the MIPI CSI-2 receiver
-  # (csi2). ceu0 has a (single) DMA engine writing captured data to memory.
-  # ceu0 node has a single 'port' node which may indicate that at any time
-  # only one of the following data pipelines can be active:
-  # ov772x -> ceu0 or imx074 -> csi2 -> ceu0.
