[RFC PATCH 5/5] xhci-pci: Use flag to not register roothub while adding primary HCD

[Kishon Vijay Abraham I]

Invoke __usb_hcd_pci_probe() without setting "register_hub" so that
primary roothub is not registered here. Instead it will be registered
along with secondary roothub. This is required for cold plugged USB
devices to be detected in certain PCIe USB cards (like Inateck USB
card).
