Eduardo Valentin 4ed1a6b6e6 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.
