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.
