ASoC: samsung: odroidx2/u3: Remove unnecessary system clock setting

This patch removes the redundant sysclk setting of odroid cpu_dai.
Since the audio working mode has been changed from I2S master mode
to I2S slave mode, so we don't need to set the cpu_dai I2S clock
mode to operation any more. Besides, the hw_params function will
set cpu_dai I2S sysclk to CDCCLK mode, which makes the cpu_dai to
use the system clock generated by audio codec max98090.
