Various changes to support QE USB Host on a MPC8360E-MDS board:

- Update the device tree per QE USB bindings;
- Configure QE Par IO;
- Set up BCSR for both USB Host and Peripheral modes;
- Add timer (GTM) node;
- Add gpio-controller node for BCSR13 bank;
- Select FSL_GTM, QE_GPIO and OF_SIMPLE_GPIO.

The work is loosely based on Li Yang's patch[1], which is used
to support peripheral mode only.

The s-o-b line of the original patch preserved here.
