The ITE IT6505 display bridge can take one I2S input and transmit it
over the DisplayPort link.
Add #sound-dai-cells (= 0) to the binding for it.

The driver side changes [1] are still being worked on, but given the
hardware is very simple, it would be nice if we could land the binding
first and be able to introduct device trees that have this.

In such case you also want to $ref /schemas/sound/dai-common.yaml.

Ack. I assume this also means I should change "additionalProperties: false"
to "unevaluatedProperties: false" in this file.
