qcom-geni-se: correct the bandwidth aggregation logic

Current aggregation logic in geni driver doesn't take "agg ab"
into consideration to put bandwidth request to bus driver. This
is a issue if QUPv3 clock is not sufficient for multiple use
cases.

Correct the logic to include "agg ab" as well into
consideration to decide next bandwidth request. Increase the
bus bandwidth ranges.
