The ignore_machine field in the component driver is used to ignore the FE DAI links defined in the machine driver, override BE fixups and set the stream names for the DAI links defined in the machine driver. This is required to make SOF compatible with the legacy machine drivers. In the case of the nocodec machine driver in SOF, there is no need to rely upon this ignore_machine logic in the core. Modify the machine driver to set DAI link stream names and the BE hw_params_fixup callback appropriately.
