Dave Jiang 592780b839 cxl: Fix retrieving of access_coordinates in PCIe path ... Current loop in cxl_endpoint_get_perf_coordinates() incorrectly assumes the Root Port (RP) dport is the one with generic port access_coordinate. However those coordinates are one level up in the Host Bridge (HB). Current code causes the computation code to pick up 0s as the coordinates and cause minimal bandwidth to result in 0. Add check to skip RP when combining coordinates.
