wifi: nl80211: reject color-change requests that change 6 GHz power type

Browse Source 
AP power type is regulatory operating state, so changing it requires
full AP reconfiguration and validation. Allowing it through
color-change could bypass stricter checks done in AP setup.

Keep color-change behavior limited to color updates only.
