lenovo/x220: Enable USB 3 controller

Since only X220 with i7 have the USB3 controller this was
    probably overlooked.

Before this patch lspci on Linux would not show the NEC USB 3 controller
    as well as the PCI bridge it is behind. After, both the bridge and the
    NEC controller can be found in the output:

05:00.0 USB controller: NEC Corporation uPD720200 USB 3.0 Host Controller
    	(rev 04)
