ASoC: SOF: ipc4-topology: Add support for effect
Merge series from Peter Ujfalusi <peter.ujfalusi@linux.intel.com>: The following series will add support for IPC4 process modules as effect widgets. We can cover wide range of modules as a generic process or effect module, the patches will lay down the fundation and the generic code to handle them. At initialization time process modules can receive additional information on top of the base_cfg, which is defined as base_cfg_ext, an extension for the base configuration struct. Other parameters or blobs for these modules are sent as a separate message via LARGE_CONFIG message, which is handled by the existing bytes control support.
