arm64: dts: freescale: imx93-phycore-som: Add watchdog ext-reset-output pin
On phyCORE-i.MX93 SoM, the SoC WDOG_ANY output line is connected to the
external pca9451a PMIC WDOG_B input. Apply pinctrl and set the property
"fsl,ext-reset-output" for watchdog to trigger board reset via PMIC on
timeout/reset.
