arm64: dts: rockchip: move DDC bus from Haikou carrierboard to RK3399 Puma DTSI

The DDC bus is necessarily on I2C3, that's how it's exposed by RK3399
Puma on the Q7 golden fingers, so let's move it to the SoM DTSI instead.

If the carrierboard doesn't route it for some reason, /delete-property/
can be used to remove it.
