introspect: Expose port info per card to clients

Browse source 
For volume control UIs to be able to show ports in inactive profiles,
expose all ports together with the card info. This includes updating
the protocol and the client API to show the connection between ports
and for which profiles the ports are relevant.

Update protocol to 26.
