ASoC: SOF: add path indirection to each IPC type

With the addition of the IPCv4, we need the ability to select
different paths for firmware and topologies.

First add an indirection. Follow-up patches will add mechanisms to
select a default IPC or override it.

No functionality change in this patch.
