The conversion of the rcar-du driver from the I2C slave encoder to the DRM bridge API left the HDMI encoder's bridge pointer NULL, preventing the bridge from being handled automatically by the DRM core. Fix it.

Dave, this is a candidate for v4.8 as the offending patch just made it upstream during the merge window.
