This works for me.. But I have kept the code as in the xhci_pci_probe(),
ofcourse removed bool renesas_device.

the xhci is not valid before invoking renesas_xhci_check_request_fw().
Is there another way to get xhci from dev without calling
usb_hcd_pci_probe().
xhci = hcd_to_xhci(hcd) doesn't seem to work before that!
