This macro integrates SOF modules into Zephyr initialisation
framework. SOF module initialisation functions use
DECLARE_MODULE_ADAPTER() or DECLARE_MODULE() to register with the SOF
native initialisation scheme, now the same initialisation functions
can be used with the new SOF_MODULE_INIT() macro to integrate them
into the Zephyr initialisation flow.
