PATCH v2 1/1 ARM: dts: nuvoton: Add OHCI node

The EHCI peripheral already exists in the devicetree, but the hardware also supports a discrete OHCI unit on the same USB PHY. Generic OHCI works fine for this device already and has been tested on real hardware.

Thanks, I've applied this to be picked up through the BMC tree.
