Actually adding such a thing blindly is dangerous.  Especially it may
conflict with the audio controller and lead to regression because both
modem and audio share the same resources. 

And, above all, you can't trust datasheet :)

In this case, however, it's likely safe to add, as other AMD
controllers have been added already.  So applied it now.
