arm64: dts: rockchip: use codec as clock master on px30-ringneck-haikou
If the codec is not the clock master, the MCLK needs to be
synchronous to both I2S_SCL ans I2S_LRCLK. We do not have that
on Haikou, causing distorted audio.
Before:
Running an audio test script on Ringneck, 1kHz
output sine wave is not stable and shows distortion.
After:
10h audio test script loop failed only one time.
That is 0.00014% failure rate.
