[PATCH] sandbox: watchdog: Avoid an error on startup

[Simon Glass]

For some time now running sandbox with -T produces an error:

   Core:  270 devices, 95 uclasses, devicetree: board
   WDT:   Not starting wdt-gpio-toggle
   wdt_gpio wdt-gpio-level: Request for wdt gpio failed: -16
   WDT:   Not starting wdt at 0
   MMC:   mmc2: 2 (SD), mmc1: 1 (SD), mmc0: 0 (SD)

Use an unallocated GPIO to avoid this.

Fixes: 1fc45d6483d ("watchdog: add pulse support to gpio watchdog driver")
