HID: cp2112: Fix driver not registering GPIO IRQ chip as threaded

Browse source

[ Upstream commit 37f5b858a6 ]

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.
