[PATCH 09/11] ASoC: SOF: topology: Skip parsing DAI link tokens if not needed

[Ranjani Sridharan]

Do not parse these tokens if they are not defined in the IPC version
specific token list. In the case of IPC4 with HDA topologies for
example, no DAI link specific tokens need to be added in topology.
