The only way this is usable is if a watchdog user binds to a particular
CPU before opening this device, and remains bound to that user.  The
irq-requesting thing is something that has changed since the driver
was originally added.

I suspect there are no users of this driver, and it should simply be
deleted.  It doesn't really fit our watchdog API.  If anyone wants to
resurect it, it's in git, your patches are in the list archives...
