RTL930x SoCs have a second serial interface UART1 which is exposed on dual-function pins shared with JTAG. The SoC defaults to the JTAG functionality after reset. Similar to existing pinmux registers, there's a separate register for that where a selector decides about JTAG vs UART. Add a now pinctrl node for that register and a pinmux node to enable UART1 functionality. Reference the pinmux in the (by default disabled) uart1 node. Without this, UART1 doesn't work when it is actually needed. This is e.g. the case with some PoE-capable switch where the PSE MCU communicates with the SoC via UART instead of I2C.
