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.

Shouldn't this also have a 'label' property ?

'label' property is not required by hdmi-connector.yaml and there
are in-tree hdmi-connector nodes that haven't got it.
I tried to find schematics for the board online, but failed.
I don't have the board to see the label printed in silk layer, either.

If anyone can provide a valid label name, I may add it.
For the Kontron board, Frieder might be able to look it up for you ?

For the MSC one, hmmm, I am not sure. Anyone ?
