The runtime PM of PCIe ports turns out to be quite fragile, as in some cases things work while in some other cases they don't and we don't seem to have a good way to determine whether or not they are going to work in advance. For this reason, avoid enabling runtime PM for PCIe ports by keeping their runtime PM reference counters always above 0 for the time being. When a PCIe port is suspended, it can no longer report events like hotplug, so hotplug below the port may not work, as in the bug report below.
