Add a new ipc_prepare() op to struct sof_ipc_tplg_widget_ops that will be used to calculate the memory usage for each widget in the pipelines associated with a PCM and prepare the widget for getting set up in the DSP. The prepare step will be used to allocate memory for the IPC payload, assign instance ID and update the config data for the widget based on the runtime PCM params. Once prepared, the setup step is used to send the IPC to create the widget in the DSP. Add an ipc_unprepare() op to unprepare the widget i.e free the memory allocated during prepare, free the instance ID etc. This should be invoked after the widget is freed. A new flag "prepared" is added to struct snd_sof_widget to track the prepared status of widgets. Also, IPC4 requires the platform_params and the runtime PCM params in order to prepare a widget for set up. So modify the signature of sof_pcm_setup_connected_widgets() and sof_widget_list_setup() to accept these as arguments.
