Split the output routing specification between SoC-internal data, specified in the rcar_du_device_info structure, and board data, passed through platform data. The DU has 5 possible outputs (DPAD0/1, LVDS0/1, TCON). SoC-internal output routing data specify which output are valid, which CRTCs can be connected to the valid outputs, and the type of in-SoC encoder for the output. Platform data then specifies external encoders and the output they are connected to. Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>
