ASoC: ti: davinci-i2s: Enable unexpected frame pulses detection 



McBSP can generate a SYNCERR when unexpected frame pulses are
detected. The driver always disables this feature and ignore the
unexpected frame pulses.

Enable the generation of SYNCERR by the McBSP. Unexpected frame
pulses are not ignored anymore.
