arm64: dts: imx91-9x9-qsb: add pinctrl for wdog3 reset
The wdog3 node enables fsl,ext-reset-output to assert an external
reset signal upon watchdog timeout, but lacks pinctrl configuration
for the physical pad.
Without proper pinctrl settings, which could cause the watchdog timeout
to fail to reset the board hardware.
Add pinctrl configuration to ensure the pin is properly muxed and
configured for external watchdog reset functionality.
