The Orange Pi Zero 3 exposes the H618 HDMI transmitter on a micro-HDMI connector. Add the connector node, wire it to the HDMI transmitter's output port, and enable the display pipeline. Tested on an Orange Pi Zero 3 (H618, 4GB): the sink's EDID is read correctly and the board drives a 1920x1080@60Hz desktop. Signed-off-by: Barzin Lotfabadi <redacted> ---
