ASoC: samsung: odroid: Change rfs value to 256

rfs is set 256 as a default value in I2S module. Due to clock rate
setting rounding errors with rfs=512 playback is almost twice faster
than original speed when the device is opened with 44.1k samplerate.
pulseaudio that uses 44.1k sinks can't play the sound properly.
