[PATCH] recognize three more usb peripheral controllers

This adds declarations for three USB peripheral controllers:

  - Two high speed USB cores that can be licensed from Mentor Graphics
    to be integrated into silicon:

      * "musbhsfc" is for peripherals only, as found in for example the
        IBM/AMCC 44EP processors.

      * "musbhdrc" is OTG-capable (dual role), and is found in various
        products including OMAP 2430 and the new DaVinci SOCs.

    The "musbh" standing for "Mentor USB Highspeed", the rest standing
    for "Function Controller" or "Dual Role Controller" (OTG-capable).

  - The full speed controller on the FreeScale MPC8272.

Adding these definitions just allows gadget driver code to handle any
controller-specific logic; controller drivers are quite separate.
