Are there any Barbarian Rage Powers that can only be accessed by specific Barbarian Archetypes?
Not that I am aware of. The rage powers listed under the individual archetypes are merely suggestions, not mandatory, restrictive or limited to that archetype in particular.
Technically the Totem Warrior Archetype limits you to only one Totem series as per the wording the APG, but that may have been changed and is beside the point. Essentially all the rage powers are available to any barbarian that meets their individual prerequisites.
