Håvard Skinnemoen 1f5b9cc9e4 USB: list atmel husb2_udc gadget controller
This identifies the driver for the Atmel HUSB2 Device Controller,
as integrated into the first AVR32 chip, the AT32AP700.

/*
* USB device controllers have lots of quirks. Use these macros in
* gadget drivers or other code that needs to deal with them, and which
* autoconfigures instead of using early binding to the hardware.
*
* This SHOULD eventually work like the ARM mach_is_*() stuff, driven by
* some config file that gets updated as new hardware is supported.
* (And avoiding all runtime comparisons in typical one-choice configs!)
*
* NOTE: some of these controller drivers may not be available yet.
