ASoC: SOF: ipc4-topology: Modify the signature of sof_ipc4_init_audio_fmt()

Only the copier needs to set the output format in its IPC payload. So
move the code to set the output format inside
sof_ipc4_prepare_copier_module() and modify the signature of
sof_ipc4_init_audio_fmt() to remove the out_format argument.
