Device IDs for AD3542R and AD3552R were swapped.

Hi Marcelo,

Agreed with the patch and that it matches the datasheets.. However
needs more info in the description so that people know how urgent the fix is.

Missing.
- Fixes tag so we know what trees need the fix (as they include the ID in
the fixes tag.
- Description of the user visible effects of this bug.

With those added I'll be happy to queue this up. Note I've just sent
a pull request for fixes, so not in a hurry for this - otherwise
I 'might' have figured out the details and added them whilst applying.

Thanks

Jonathan
