ASoC: SOF: add definitions for different IPC types

Browse Source 
Add enum type to allow for different types of IPCs. The IPCv4 is
intended for Intel only as a convergence path with firmware used in
Windows. Follow-up patches will introduce different abstractions with
.ops and different search paths for firmware and topology files.
