PCI: xgene: Allow config access to Root Port even when link is down
Previously, when a Root Port's link was down, we didn't allow config access to the Root Port, which meant that if the Root Port led to an empty slot, "lspci" didn't even show the Root Port. Allow config access to Root Port even when link is down.
