Subject[PATCH] usb: xhci: make symbols static
Date
When renesas module is not built, we get compiler warning on xhci driver
with W=1

CC [M] drivers/usb/host/xhci-rcar.o
drivers/usb/host/xhci-pci.h:13:5: warning: no previous prototype for ‘renesas_xhci_check_request_fw’ [-Wmissing-prototypes]
int renesas_xhci_check_request_fw(struct pci_dev *dev,
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~
drivers/usb/host/xhci-pci.h:19:6: warning: no previous prototype for ‘renesas_xhci_pci_exit’ [-Wmissing-prototypes]
void renesas_xhci_pci_exit(struct pci_dev *dev) { };
^~~~~~~~~~~~~~~~~~~~~

We have defined these symbols when CONFIG_USB_XHCI_PCI_RENESAS is not
defined, but missed making then static.
