Subject: [PATCH] usb: xhci: only set D3hot for pci device
Xhci driver cannot call pci_set_power_state() on non-pci xhci host
controllers. For example, NVIDIA Tegra XHCI host controller which acts
as platform device with XHCI_SPURIOUS_WAKEUP quirk set in some platform
hits this issue during shutdown.
