watchdog: gpio_wdt: Add option for early registration
In some situation, mainly when it's not possible to disable a
watchdog, you may want the watchdog driver to be started as soon
as possible.
Adding GPIO_WATCHDOG_ARCH_INITCALL to raise initcall from
module_init to arch_initcall.
This patch require watchdog registration deferral mechanism
