ramips: remove generic profiles

ramips: remove generic profiles

On a platform with many very different devices, like found on ramips,
the generic profiles seem like remnants of the past that do not
have a real use anymore.

Remove them to have one thing less to maintain.

Actually, rt288x didn't have a default profile in the first place.
