ASoC: fsl_micfil: Add sample rate constraint

On some platforms, for example i.MX93, there is only one
audio PLL source, so some sample rate can't be supported.
If the PLL source is used for 8kHz series rates, then 11kHz
series rates can't be supported.

So add constraints according to the frequency of available
clock sources, then alsa-lib will help to convert the
unsupported rate for the driver.
