nit: this is easily missed here inmidst of the other stuff, best place
it at the end of the node as many other nodes do.

The resets aren't mentioned in the binding, should they be added?

in difference to the other nodes the soundwire ones don't have
'status = "disabled"', should they be disabled by default?

>From the binding
- interrupt-names:
Usage: Optional
Value type: boolean
Value type: <stringlist>
Definition: should be "core" for core and "wakeup" for wake interrupt.
Does the binding need an update?
