From: Bard Liao yung-chuan.liao@linux.intel.com

The corresponding IPC4 module of snd_soc_dapm_buffer widget is module -to-module copier. The module-to-module copier is a buffer-like component with demuxing capabilities. Rename the host_token_list to common_copier_token_list since it will be used by host copier and module-to-module copier. The setup callback is almost the same as sof_ipc4_widget_setup_pcm except the gtw_cfg data, and the free callback is exactly the same as sof_ipc4_widget_free_comp_pcm. To reduce the duplication, the commit reuses the setup and free callbacks.
