Subject: [PATCH] ARM: dts: nuvoton: Add OHCI node

From: "William A. Kennington III" <wak@...gle.com>

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.
