[PATCH v1 1/2] regulator: pf9453: Respect IRQ trigger settings from firmware

[Franz Schnyder]

From: Franz Schnyder <franz.schnyder@xxxxxxxxxxx>

The datasheet specifies, that the IRQ_B pin is pulled low when any
unmasked interrupt bit status is changed, and it is released high once
the application processor reads the INT1 register. As it specifies a
level-low behavior, it should not force a falling-edge interrupt.

Remove the IRQF_TRIGGER_FALLING to not force the falling-edge interrupt
and instead rely on the flag from the device tree.
