ASoC: mediatek: mt8183-da7219: fix wrong ops for I2S3
[ Upstream commit ebb11d1d9fe2d6b4a47755f7f09b2b631046e308 ]
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.
