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 6ccfd22052444d72a12f095540275af03517136c
"Intel xhci: refactor EHCI/xHCI port switching"
