Remove 'port_type' field in struct pcie_port_data(), because we can get port type information from struct pci_dev. With this change, this patch also does followings: - Remove struct pcie_port_data because it no longer has any field. - Remove portdrv private definitions about port type (PCIE_RC_PORT, PCIE_SW_UPSTREAM_PORT and PCIE_SW_DOWNSTREAM_PORT), and use generic definitions instead.
