Add support of the device tree probing for the Renesas R-Car generation 2 SoCs
documenting the device tree binding as necessary.
You've popped in some fixes for the driver probe in here as well.
Could you do the fixes as a patch and send those before the devicetree
code is done?

Can be removed, just add a clock-name of usbhs in the device node.

Probably should be separate patch to fix probe issues.

Again, should have been rolled into fix patch.
