[PATCH v2 5/6] software node: Introduce SOFTWARE_NODE_REFERENCE() helper macro

[Andy Shevchenko]

This is useful to assign software node reference with arguments
in a common way. Moreover, we have already couple of users that
may be converted. And by the fact, one of them is moved right here
to use the helper.
