We must ping the watchdog from the kernel until the userspace handles it. MPC83xx CPUs are only differ in a way that watchdog could be disabled once, but after it was enabled via software it becomes just the same as MPC86xx. Thus, to support MPC86xx I added the kernel timer which pings the watchdog until the userspace opens it. Since we implemented the timer, now we're able to implement proper handling for the CONFIG_WATCHDOG_NOWAYOUT case, for MPC83xx and MPC86xx. Also move the probe code into subsys_initcall, because we want start pinging the watchdog ASAP, and misc devices are available in subsys_initcall.
