cpu-o3: Make the smtLSQPolicy a Param.ScopedEnum
The smtLSQPolicy is a parameter in the o3 cpu that can have 3
different values. Previously this setting was done through a string
and a parser function would turn it into a c++ enum value. This
changeset turns the string into a python Param.ScopedEnum.
