Add samsung,vbus-gpio information for the XU3. This allows the usage of the EHCI controller on the XU3, which is connected to the SMSC LAN9514 chip (usb hub + network).
Note that this patch doesn't enable support for USB/USB networking in the default config as makes the u-boot binary too big for the current odroid setup.

Are you sure this is right? By my count this should be 0x66, not 0x316. This might be historical.
It almost feels like you could drop this patch until you actually have working USB support.
