ASoC: SOF: IPC: Introduce IPC ops

In preparation for supporting a new IPC version that will be introduced
in the SOF firmware, add a new set of ops that will be version specific.

For now, the IPC ops contain only the topology-related ops for setting
up widgets and pipeline connections. It will be expanded later to also
abstract the IPC-specific items in the component driver and DAI driver.
