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 1672d28392124d6a155fa4f3c0fb7a060c96b5fe
"Intel xhci: refactor EHCI/xHCI port switching"
