Calculate and store the performance data for a CXL region. Find the worst read and write latency for all the included ranges from each of the devices that attributes to the region and designate that as the latency data. Sum all the read and write bandwidth data for each of the device region and that is the total bandwidth for the region. The perf list is expected to be constructed before the endpoint decoders are registered and thus there should be no early reading of the entries from the region assemble action. The calling of the region qos calculate function is under the protection of cxl_dpa_rwsem and will ensure that all DPA associated work has completed.
