arm64: dts: rockchip: Move uart5 pin configuration to px30 ringneck SoM
In the PX30-uQ7 (Ringneck) SoM, the hardware CTS and RTS pins for
uart5 cannot be used for the UART CTS/RTS, because they are already
allocated for different purposes. CTS pin is routed to SUS_S3#
signal, while RTS pin is used internally and is not available on
Q7 connector. Move definition of the pinctrl-0 property from
px30-ringneck-haikou.dts to px30-ringneck.dtsi.
This commit is a dependency to next commit in the patch series,
that disables DMA for uart5.
