Combine USB code for all PortalPlayer targets since they most likely all use the same USB hardware. Add register defines for the USB hardware addresses, based off the Freescale i.MX31 datasheet. Use usb_init() from the iPod code, but modified to use the new register defines rather than oul/inl on the hardware addresses.
