utils: gen-controls: Fix enumerators documentation

The Doxygen documentation for enumerators prefixes the enumerator name
with the enumeration name. For unscoped enumerations, this is incorrect.
Drop the scope. This fixes warnings produced by Doxygen when multiple
enumerators with identical names are defined in different scopes.
