ARM: dts: imx51-zii-rdu1: limit usbh1 to full-speed

Browse Source 
On RDU1, imx51 usbh1 interface is either not used, or used via external
block that breaks USB2 signalling.

To keep things working if high-speed device gets connected to that
block, use ChipIdea feature to limit port to full speed.
