[PATCH] ASoC: samsung: i2s: Supported high resolution rates

[Jaechul Lee]

This driver can support more frequencies over 96KHz. There are no reasons
to limit the frequency range below 96KHz. If codecs/amps or something else
can't support high resolution rates, the constraints would be set rates
properly because each drivers have its own limits.
