xhci: Cleanups, non-urgent fixes for 3.14.

Happy Holidays, Greg!

Here's four patches to be queued to usb-next for 3.14.

One adds a module parameter to the xHCI driver to allow users to enable
xHCI quirks without recompiling their kernel, which you've already said
is fine.  The second patch is a bug fix for new usbtest code that's only
in usb-next.  The third patch is simple cleanup.

The last patch is a non-urgent bug fix for xHCI platform devices.  The
bug has been in the code since 3.9.  You've been asking me to hold off
on non-urgent bug fixes after -rc4/-rc5, so it can go into usb-next, and
be backported to stable once 3.14 is out.

These have all been tested over the past week.  I did run across one
oops, but it turned out to be a bug in 3.12, and therefore not related
to any of these patches.

Please queue these for usb-next and 3.14.

usb: xhci: Check for XHCI_PLAT in xhci_cleanup_msix()

If CONFIG_PCI is enabled, make sure xhci_cleanup_msix()
doesn't try to free a bogus PCI IRQ or dereference an invalid
pci_dev when the xHCI device is actually a platform_device.

This patch should be backported to kernels as old as 3.9, that
contain the commit 52fb61250a7a132b0cfb9f4a1060a1f3c49e5a25
"xhci-plat: Don't enable legacy PCI interrupts."
