I guess it is such a simple device that no one has proposed
anything like an API.

I would not be opposed to an API for a watchdog timer.  I
don't see much of an API though since there isn't that much
functionality. 

+ enable with expiration
+ reset
+ disable
+ is enabled?

But a standard API, no matter how simple encourages portability.
