ASoC: SOF: Introduce optional callback to configure stream data offset

Browse Source 
Each running audio stream's data have distinct start offset within the
stream mailbox area from/to where the host can read/write.

Instead of using the struct sof_ipc_pcm_params_reply to configure this
offset, add an optional callback which is IPC agnostic.
