watchdog: aspeed: add nowayout support
Add support for not stopping the watchdog when the userspace application quits. At closing of the device, the driver cannot determine if this was a graceful closure or if the app crashed. If the support of nowayout on this driver, the system integrator can select the behaviour by setting the kernel config and enabling it.
