[PATCH 3/3] ARM: dts: imx7s-warp: Use WDOG_B pin reset

[festevam@gmail.com (Fabio Estevam)]

From: Fabio Estevam <fabio.estevam@nxp.com>

imx7s-warpd has WDOG1_B pin connected to the PMIC.
    
Pass the 'fsl,ext-reset-output' property so that the watchdog
can trigger a system POR reset via the PMIC.
