This one is different to the BT case - as you say it's hanging off the
HDMI controller so the HDMI controller ought to enumerate it either as a
stub or by actually seeing a device. The platform device is fine but
it's not something that should appear in the DT unless it's conveying
some information about what's connected there (eg, power supplies for
something soldered down on the board).
