mfd: rk808: set fall event higher priority than rise event

Browse Source 
When PMIC irq occurs, regmap-irq.c will traverse all PMIC child
interrupts from low index 0 to high index, we give fall interrupt
high priority to be called earlier than rise, so that it can be
override by late rise event. This can helps to solve key release
glitch which make a wrongly fall event immediately after rise.
