Extend ipc stream parameters sent to DSP
Merge series from Daniel Baluta <daniel.baluta@oss.nxp.com>

From: Daniel Baluta <daniel.baluta@nxp.com>
We need a way to send extra parameters to DSP firmware. In order to do
this, we introduce ext_data array at the end of ipc_stream_params.
With this new addition we can send compress parameters.
This requires SOF ABI bump.
