TSD: arm64: dts: rockchip: reduce m25p40 spi nor flash freq on ringneck-haikouHEADv6.6.39-puma
spi-max-frequency was set to 75MHz, which actually gets you 50MHz on the
bus as verified with an oscilloscope.
At 50MHz, data transfers are flakey with some q7 connector savers.
Running a flashcp loop throws verify errors every now and then.
Reduce freq to 10MHz which is stable also with the q7 connector saver.
Note that this is needed *in addition* to the spi1 cs-gpios fix.
