Hardware-based synchronization is typically required when the bus->multi_link flag is set. On Intel platforms, when the Cadence IP is configured in 'Multi Master Mode', the hardware synchronization is required even when a stream only uses a single segment. The existing code only deal with hardware synchronization when a stream uses more than one segment so to remain backwards compatible we add a configuration threshold. For Intel cases this threshold will be set to one, other platforms may be able to use the SSP-based sync in those cases.
