Sarah Sharp 671e3aaf0c xhci: Avoid dead ports when CONFIG_USB_XHCI_HCD=n 
Commit 51c9e6c773 upstream, but modified
to get this to apply on 3.0.

If the user chooses to say "no" to CONFIG_USB_XHCI_HCD on a system
with an Intel Panther Point chipset, the PCI quirks code or the EHCI
driver will switch the ports over to the xHCI host, but the xHCI driver
will never load.  The ports will be powered off and seem "dead" to the
user.

Fix this by only switching the ports over if CONFIG_USB_XHCI_HCD is
either compiled in, or compiled as a module.

This patch should be backported to the 3.0 stable kernel, since it
contains the commit 69e848c209 "Intel
xhci: Support EHCI/xHCI port switching."
