ASoC: SOF: ipc4-topology: Fix the output reference params for SRC

Browse source 
For playback, the SRC sink rate must be configured based on the requested
output format which is restricted to only handle DAI's that support a
single audio format for now. For capture, the SRC module should convert
the rate to match the rate requested by the PCM hw_params.
