[v2,15/15] ASoC: dt-bindings: renesas,rsnd.yaml: enable multi ports for multi Component support

To enable multi Component support, "multi ports" is needed for Audio Graph
Card/Card2, and "multi rcar_sound,dai" is needed for Simple Audio Card.
This patch enable these.

With a unit-address you need a 'reg' property.

Multiple 'ports' nodes is not valid.

Here too would need a 'reg' property. Did you test any of this because 
that would be a dtc warning.

I don't remember detail, but some reviewer indicated that it is not needed,
because we have default "reg" property somewhere/somehow.


Thank you for your help !!
