The BE DAI driver ops involve operations that are IPC-specific. For ex: for the HDA DAI, the trigger op involves sending the DAI_CONFIG IPC to the DSP to stop the DMA for the stop/pause commands. This sequence is different for IPC3 and IPC4. So, make the dai driver ops IPC-specific and set the IPC3-specific ops during the ops_init() callback.
