Documentation: RCU: Reduce toctree depth
toctree index for RCU currently has maximum depth of 3. Since no docs
currently use more than 3 section heading levels, this effectively spills
the entire docs hierarchy.
Tidy up by reducing toctree depth to 2 (only showing docs title and
second-level sections).
