Currently the codec is going to be reset at every stream start, since it can get
confused, if I fail to do that, especially, when the FIFO is enabled.
In case, when the bypass was not enabled the codec anyway will hit BIAS_OFF, so
next time, when we power it on, it is going through the power-up sequence.
I do have some plans to actually remove the need for this reset requirement at
every stream start (it adds considerable amount of latency, and other unwanted
I can resend the patch with updated changelog.
