ASoC: audio-graph-card: remove ports node name check

Current audio-graph-card is checking if the node name was "ports" or
not when parsing the property.

	if (of_node_name_eq(ports, "ports"))
		of_xxx(ports, ...);

Now, it is using new port_to_ports() which will be NULL if the node
doesn't have "ports", and each of_xxx functions will do nothing if
node was NULL.
Now we don't need to check ports node name. Let's remove and cleanup it.
