It should only be called when we own the PCIe native hotplug and not the AER ownership 2. It should only manipulate the AER-bits In addition, the second commit adds a warning if the _HPX type2 record attempts to modify the Link Control register. The programming of the device's RCB is constrained to the device types where it is applicable and also skips VFs. If the Root Port's RCB cannot be determined, we also skip the programming of the device's RCB. Then, we program the device's RCB according to the Root Port's setting.
