ARM: dts: Enable USB hub on Arndale
The Arndale has a SMSC USB3503 connected in hardware only mode like a PHY, support it using the usb-nop-xceiv binding. Note that due to a regrettable decision to use a regulator to represent the reset signal this uses a fixed voltage regulator to do that, there is a plan to use the reset controller binding once that is merged so it does not seem worthwhile to fix the usb-nop-xceiv driver at this point.
