In that case, we don't need this work around I guess.
At maximum during boot time, we may see few sound card registration failure logs,
Which is normal.

With this change, our concept of ACP parent device which will create platform devices
for DMA driver, Generic DMIC driver and Machine driver will be changed.
We implemented same design for Raven I2S driver as well which got productized.
