The Freescale MX27 and MX31 SoCs have a EHCI controller onboard. The controller is capable of USB on the go. This patch adds a driver to support all three of them. Users have to pass details about serial interface configuration in the platform data. The USB OTG core used here is the ARC core, so the driver should be renamed and probably be merged with ehci-fsl.c eventually.
