ASoC: SOF: Add two new fields to struct snd_sof_widget

Browse source 
Add two new fields, instance_id and module_info to struct
snd_sof_widget. instance_id for widgets will be assigned when they are
set up in the DSP and reset when the widgets are freed. module_info is
used to save information the firmware provides about each module in its
manifest.
