regulator: pca9450: Correct interrupt type

Browse source

[ Upstream commit 5d0efaf47e ]

Kernel warning on i.MX8MP-EVK when doing module test:
irq: type mismatch, failed to map hwirq-3 for gpio@30200000!

Per PCA945[X] specification: The IRQ_B pin is pulled low when any unmasked
interrupt bit status is changed and it is released high once application
processor read INT1 register.

So the interrupt should be configured as IRQF_TRIGGER_LOW, not
IRQF_TRIGGER_FALLING.
