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.
