Subject: [PATCH v2] gpio: pca953x: Don't hardcode irq trigger type

Don't hardcode irq trigger to IRQF_TRIGGER_LOW while registering IRQ
handler. IRQ/platform core will take care of setting appropriate trigger
type.

Signed-off-by: Vignesh Raghavendra <vigneshr@...com>

v2:
Drop explicit call to irq_get_trigger_type() as this is take care of in core
code.
