[PATCH v4 03/21] ASoC: fsl_micfil: drop fsl_micfil_set_mclk_rate()

[Sascha Hauer <s.hauer@pengutronix.de>]

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.
