Yeah, so you're right. I've taken the guards off everything except the
new API function. I still want to leave the patch that adds the symbol
at the end: that way you don't get the function unless it is actually
going to make a difference in the EEH process. 

The other driver (cxlflash) just guards the API function, inserting a
stub if it's not defined. So this setup will make our code cleaner and
will still let their code merge cleanly.

Thanks again for the review.
