ARM: dts: imx7s-warp: Use WDOG_B pin reset
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. Signed-off-by: Fabio Estevam <fabio.estevam@nxp.com> Signed-off-by: Shawn Guo <shawnguo@kernel.org>
