ASoC: SOF: sof-audio: Fix broken early bclk feature for SSP 

With the removal of widget setup during BE hw_params, the DAI config IPC
is never sent with the SOF_DAI_CONFIG_FLAGS_HW_PARAMS. This means that
the early bit clock feature required for certain codecs will be broken.

Fix this by saving the config flags sent during BE DAI hw_params and
reusing it when the DAI_CONFIG IPC is sent after the DAI widget is set
up. Also, free the DAI config before the widget is freed.

The DAI_CONFIG IPC sent during the sof_widget_free() does not have the
DAI index information. So, save the dai_index in the config during
hw_params and reuse it during hw_free.

For IPC4, do not clear the node ID during hw_free. It will be needed for
freeing the group_ida during unprepare.
