usb: pci-quirks: Prevent Sony VAIO t-series from switching usb ports



Sony VAIO t-series machines are not capable of switching usb2 ports over
from Intel EHCI to xHCI controller. If tried the USB2 port will be left
unconnected and unusable.

This patch should be backported to stable kernels as old as 3.12,
that contain the commit 26b76798
"Intel xhci: refactor EHCI/xHCI port switching"
