[PATCH 1/4] dt-bindings: media: sun4i-a10-video-engine: Add interconnect properties

[Chen-Yu Tsai <wens@kernel.org>]

The Allwinner video engine sits behind the MBUS that is represented as
an interconnect.

Make sure that the interconnect properties are valid in the binding.

Fixes: d41662e52a03 ("media: dt-bindings: media: allwinner,sun4i-a10-video-engine: Add R40 compatible")
