powerpc/85xx: Add QE USB support for MPC8569E-MDS boards
- Add gpio-controller node for BCSR17, it is used to control USB
speed and VBUS;
- Add timer node for QE GTM, needed for USB host;
- Add usb node itself;
- Add some probing code for BCSR GPIOs.
NOTE: QE USB doesn't work on prototype boards, but should work on
pilot boards if specs and schematics are correct, though we
don't have the pilot boards to actually test it.
