ASoC: SOF: Prepare ipc_msg_data to be used with compress API

Make second parameter of ipc_msg_data generic
in order to be able to support compressed streams.

This patch doesn't hold any functional change.

With this case we can use ipc_msg_data, to retrieve information from
DSP for both PCM/Compress API.
