cxl: Add helper function that calculate performance data for downstream ports
The CDAT information from the switch, Switch Scoped Latency and Bandwidth
Information Structure (SSLBIS), is parsed and stored under a cxl_dport
based on the correlated downstream port id from the SSLBIS entry. Walk
the entire CXL port paths and collect all the performance data. Also
pick up the link latency number that's stored under the dports. The
entire path PCIe bandwidth can be retrieved using the
pcie_bandwidth_available() call.
