Add helpers to determine if a page or folio is a device dax or fs dax
page or folio.

... why is it "device_dax" but "fsdax" ? In particular because you wrote 
"fs dax" above.

I see "fsdax" getting used in some functions. But then, people usually 
say "devdax".

I'm fine either way (could be cleaned up later), just wondering about 
that slight "inconsistency".

So whatever you think is best, feel free to add
