ASoC: SOF: ipc3-topology: Make sure that only one cmd is sent in dai_config
The commands in sof_ipc_dai_config.flags are encoded as bits:
1 (bit0) - hw_params
2 (bit1) - hw_free
4 (bit2) - pause
These are commands, they cannot be combined as one would assume, for
example
3 (bit0 | bit1) is invalid.
This can happen right at the second start of a stream as at the end of the
first stream we set the hw_free command (bit1) and on the second start we
would OR on top of it the hw_params (bit0).
