ASoC: SOF: add definitions for different IPC types
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.
