INTRNG - update gpio pin capabilities according to r299166.

Browse Source 
Note that the updated comment is valid only for INTRNG. This should not
be a problem as not INTRNG code is left in place for debugging reasons
only and should not be used anymore. It's anticipated that this old
code will be removed soon.
