xhci: Set HCD flag to defer primary roothub registration
Set "HCD_FLAG_DEFER_RH_REGISTER" to hcd->flags in xhci_run() to defer registering primary roothub in usb_add_hcd(). This will make sure both primary roothub and secondary roothub will be registered along with the second HCD. This is required for cold plugged USB devices to be detected in certain PCIe USB cards (like Inateck USB card connected to AM64 EVM or J7200 EVM).
