DA7219 uses I2S2 and I2S3 for input and output respectively. Commit 9e30251fb22e ("ASoC: mediatek: mt8183-da7219: support machine driver with rt1015") introduces a bug that: - If using I2S2 solely, MCLK to DA7219 is 256FS. - If using I2S3 solely, MCLK to DA7219 is 128FS. - If using I2S3 first and then I2S2, the MCLK changes from 128FS to 256FS. As a result, no sound output to the headset. Also no sound input from the headset microphone.

Both I2S2 and I2S3 should set MCLK to 256FS. Fixes the wrong ops for I2S3.
