ASoC: SOF: topology: Make pga widget parsing IPC agnostic 

Define the list of tokens pertaining to the pga type widgets, parse and
save them as part of the swidget tuples array. Once topology parsing is
complete, these tokens will be applied to create the IPC structure for the
pga component based on the topology widget_setup op in ipc3_tplg_ops.
