interconnect: qcom: icc-rpm: Set bandwidth and clock for bucket values

This commit uses buckets for support bandwidth and clock rates.  It
introduces a new function qcom_icc_bus_aggregate() to calculate the
aggregate average and peak bandwidths for every bucket, and also it
calculates the maximum value of aggregated average bandwidth across all
buckets.

The maximum aggregated average is used to calculate the final bandwidth
requests.  And we can set the clock rate per bucket, we use SLEEP bucket
as default bucket if a platform doesn't enable the interconnect path
tags in DT binding; otherwise, we use WAKE bucket to set active clock
and use SLEEP bucket for other clocks.  So far we don't use AMC bucket.
