mfd: max77759: Drop use of irqd_get_trigger_type

irqd_get_trigger_type() is meant for cases where the driver needs to
know the configured IRQ trigger type and e.g. wants to change its
behaviour accordingly. Furthermore, platform support code, e.g. DT
handling, will configure the hardware based on that, and drivers don't
need to pass the trigger type into request_irq() and friends.

Drop the use from this driver, as it doesn't need to know the trigger
type.
