From: Ranjani Sridharan <ranjani.sridharan@linux.intel.com>

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.
