arm64: dts: rockchip: set codec system-clock-fixed on px30-ringneck-haikou

Having sgtl5000_clk defines as "fixed-clock" is not enough to prevent
the dai subsystem from overwriting the frequency via sgtl5000_set_dai_sysclk.

Setting system-clock-fixed does the job, and now a 1kHz sine wave
comes out as actually 1kHz, no matter the sample rate of the source.

Testcase: These should sound the same:

speaker-test -r 48000 -t sine -f 1000
speaker-test -r 24000 -t sine -f 1000

Also remove the clock link here as having it in sgtl5000 and
sgtl5000_codec causes duplicate clock unprepares with associated
backtrace.

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.
