ARM: at91/dt: sam9n12ek: ohci: add port and vbus property
Add the port number and vbus property for ohci port, or else if bootloader won't configure the vbus pin, the 5v supply is not power on, so can not work with usb devices. Signed-off-by: Bo Shen <voice.shen@atmel.com> Signed-off-by: Nicolas Ferre <nicolas.ferre@atmel.com>
