arm64: dts: rockchip: enable I2S0 in Haikou carrierboard, not Puma DTSI

I2S0 is routed to the Q7 golden fingers and, on Haikou carrierboard, to
an I2S codec. Nothing aside from signal routing is done on the SoM,
therefore it's the duty of the carrierboard to enable I2S0 whenever an
I2S codec is present.

Such is the case of the Haikou carrierboard, therefore let's migrate the
enabling of this controller to the carrierboard DTS instead of the SoM
DTSI.
