For non PCI-based stacks, this function call
usb_disable_xhci_ports(to_pci_dev(hcd->self.controller));
made from xhci_shutdown is not applicable.
Ideally, we wouldn't have any PCI-specific code on
a generic driver such as the xHCI stack, but it looks
like we should just stub usb_disable_xhci_ports() out
for non-PCI devices.
[ balbi@ti.com: slight improvement to commit log ]
This patch should be backported to kernels as old as 3.0, since the
commit it fixes (e95829f474 "xhci: Switch
PPT ports to EHCI on shutdown.") was marked for stable.
