regulator: pf9453: Respect IRQ trigger settings from firmware
commit 2d85ecd6fb0eb2fee0ffa040ec1ddea57b09bc38 upstream.
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.
