All that the .set_sysclk hook in the micfil driver does is to pass the sysclk frequency to fsl_micfil_set_mclk_rate(). This function expects the sample rate as argument though, not any kind of sysclk frequency. The resulting rate setting of the clock is overwritten in hw_params anyway, so drop this altogether.
