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.
