ASoC: SOF: topology: Add helper function for processing tuple arrays
Add a helper function for processing tuple arrays and populating the
IPC structure objects based on the token ID passed.
Introduce a new enum representing token ID for the tokens
currently used in the topology parse and a new struct sof_token_info
to store the information about a token set. Finally, expose the struct
snd_sof_topology token as it will be used by IPC-specific code.
