[PATCH 2/2] arm64: dts: allwinner: orangepi-zero3: enable HDMI output

[Barzin Lotfabadi <barzin221@gmail.com>]

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.
