Subject: [PATCH 2/5] arm64: dts: imx8mp-kontron-smarc-eval-carrier: Add HDMI connector

Add a HDMI connector to connect with i.MX8MP HDMI TX output.
This is a preparation for making the i.MX8MP LCDIF driver use
drm_bridge_connector which requires the DRM_BRIDGE_ATTACH_NO_CONNECTOR
flag.  With that flag, the DW HDMI bridge core driver would
try to attach the next bridge which is the HDMI connector.
