drm/rcar-du: Add platform module device table
The platform device id driver data field points to a device information structure that only contains a (currently empty) features field for now. Support for additional model-dependent features will be added later. Only the R8A7779 variant is currently supported. Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>
