[media] adv7180: Pass correct flags to request_threaded_irq()

Browse source 
Most IRQ controllers support different types of interrupts. The adv7180
generates falling edge interrupts, so make sure to pass IRQF_TRIGGER_FALLING
to request_threaded_irq() so the IRQ controller is configured for the
correct mode.
