drm/rcar-du: Add FBDEV emulation support
Use the FB CMA helpers to implement FBDEV emulation support. The VGA connector status must be reported as connector_status_connected instead of connector_status_unknown to be usable by the emulation layer. Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>
