The r8a77965 M3-N platform supports a DPAD, HDMI and LVDS output, along 3 DU channels. However, DU2 is not available in the hardware, with the DPAD instead being routed through DU3.
Provide support for this non-linear indexing with updates to the rcar-du driver, before adding the device info structure for the r8a77965.
