Not likely: Clonus is not typically felt to be normal and is usually associated with underlying spasticity, which can have a number of potential causes. Certainly a full neurological work up is indicated if he truly has clonus.

Probably normal: Many infants will have ankle clonus. It can take a few years to go away. Disturbing signs would include worsening clonus, difficulty with balance or coordination, and not achieving other normal developmental milestones on time. If these occur,see a doctor urgently.
