Add a new optional renesas,companion property to point to the companion LVDS encoder. This is used to support dual-link operation where the main LVDS encoder splits even-numbered and odd-numbered pixels between the two LVDS encoders.
The new property doesn't control the mode of operation, it only describes the relationship between the master and companion LVDS encoders.
