mfd: rn5t618: Fix IRQ trigger by changing it to level mode
[ Upstream commit a1649a5260631979c68e5b2012f60f90300e646f ] During more massive generation of interrupts, the IRQ got stuck, and the subdevices did not see any new interrupts. That happens especially at wonky USB supply in combination with ADC reads. To fix that trigger the IRQ at level low instead of falling edge.
