ASoC: samsung: odroidx2: Handle I2S CDCLK clock conditionally
In order to support old DTs we check the codec device node if it contains "clocks" property and only if it doesn't (which indicates an old DT) we proceed with enabling the CDCLK clock by means of the set_sysclk() callback. For new DTs which use the common clock bindings for CDCLK that clock is supposed to be handled outside the sound machine driver.
