This actually makes the IRQ trigger values consistent with the drivers, that
define them regardless of devicetree anyway. The max98090 driver
hasÂIRQF_TRIGGER_FALLING and bq24735 has IRQF_TRIGGER_RISING |
IRQF_TRIGGER_FALLING.

This is really more of a cosmetic change, it doesn't impact actual use.
