David Moore 58b2939b4d usb: Prevent dead ports when xhci is not enabled 
When the xHCI driver is not available, actively switch the ports to EHCI
mode since some BIOSes leave them in xHCI mode where they would
otherwise appear dead.  This was discovered on a  Dell Optiplex 7010,
but it's possible other systems could be affected.

This should be backported to kernels as old as 3.0, that contain the
commit 69e848c209 "Intel xhci: Support
EHCI/xHCI port switching."
