clk: qcom: branch: Fix propagation of parent rate to branches



Currently the recalc rate of the branches is broken and it reports 0.
Ideally the rate would be the parent rate, except where the aggregation
is required for sibling branches.
Also in the cases where a clock rate is set on a branch or rcg the rate
of the parent should get propagated to each of the sibling/child branches.
Fix this propagation in the cases where aggregation is not a
requirement on the branches.
