arm64: dts: renesas: falcon-csi-dsi: Set bus-type for MAX96712

Specify the bus-type property for all three connected MAX96712.

The default behavior when parsing a node without this property is to
default to D-PHY.  Making this explicit plays it safe and future proofs
things as the default parsing comes from the V4L2 core and not the
driver itself.
