    This is an update to the AT91 USB Device (Gadget) driver.
    
    Adds support for the Atmel AT91SAM9260 and AT91SAM9261 processors.  The
    only difference is how they handle the pullup pin.
    [Patch from Patrice Vilchez]
    
    Need to clear any pending USB Device interrupts before registering the
    interrupt handler.  The bootloader might have been using the USB Device
    port.   [Patch from Peer Georgi]
    
    VBUS detection is handled by a GPIO interrupt which only triggers on a
    change. Is is therefore necessary to read the current VBUS state
    explicitly at startup.  [Patch from Peer Georgi]
