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.

This doesn't 100% work right now since we don't yet have a solution to ensure that this gets started after the USB controller but those modifications are small (or can be done at runtime with module loading).

ehci-s5p driver doesn't use 'usb-phy' property to find the PHY driver, hence this is not required.
