We need to reuse cl_prepare, cl_trigger and cl_cleanup helpers from a SoundWire context where only the device information is available. Rather than pass the 'sdev' argument, use get_drvdata() to retrieve the required structure.
For consistency, rename hda_cl_stream_prepare() as hda_cl_prepare().
These three helpers are also exported so that they can be referenced from another module.
