Subject: [PATCH 1/1] pci: xgene: Fix compilation warning

commit 979595bcb8da ("PCI: xgene: Allow config access to Root Port even
when link is down") removes the port->link_up check, which makes 'port'
become unused variable. This patch remove struct xgene_pcie_port *port
declaration to avoid compilation warning.
