ASoC: SOF: pcm: Make hw_params reset conditional for IPC3
In the case of IPC4, since there is no PCM_PARAMS IPC to send the new
stream tag when restarting a stream without a hw_free, the original
stream tag needs to be preserved. So, add new a flag as part of struct
sof_ipc_pcm_ops, reset_hw_params_during_stop and set it only for IPC3.
This will ensure that the host DMA stream tag will not be given up during
the STOP trigger for IPC4.
