I don't think any other in-kernel watchdog driver has to deal with
write-once hardware.  On these processors once the watchdog register
is programmed, it cannot be disabled or re-programmed.
If the above behaviour is required, then we might aswell remove the
ioctl(WDIOC_SETTIMEOUT) interface for this driver since if the user
wants anything other than the default timeout they would need to pass
it via the kernel command-line or module parameters.
