    HID: cp2112: Fix driver not registering GPIO IRQ chip as threaded
    
    [ Upstream commit 37f5b858a66543b2b67c0288280af623985abc29 ]
    
    The CP2112 generates interrupts from a polling routine on a thread,
    and can only support threaded interrupts. This patch configures the
    gpiochip irq chip with this flag, disallowing consumers to request
    a hard IRQ from this driver, which resulted in a segfault previously.
