mb/lenovo/x220: Correct USB port config

Browse source 
- Drop USB OC2#, OC3#, OC4#, OC6#
  Those are either pulled high or used as GPIO and used by internal
  devices only.
- Disable Port 4, 6, 7. They are unused.
- Add comments with devices connected.

TEST=On Lenovo x220 the USB ports P00, P01, P02, P03, P08, P09, P11,
     P13 are still working.
