ASoC: samsung: i2s: Define the parameters list for SAMSUNG_I2S_OPCLK
The SAMSUNG_I2S_OPCLK is not currently used by any card driver thus we can safely change semantics of 'dir' argument of the I2S set_sysclk() callback. Now an enumeration is exported instead of directly using register bit field values.
