[PATCH v2 25/26] soundwire: intel: remove .free callback implementation

[Bard Liao <yung-chuan.liao@xxxxxxxxxxxxxxx>]

From: Pierre-Louis Bossart <pierre-louis.bossart@xxxxxxxxxxxxxxx>

The interface is not needed for IPC3 solution but will be needed with
an updated parameter list for ACE2.x+IPC4 combinations.
