pinctrl: npcm8xx: move GPIO IRQ setup into request_resources

Browse source

npcmgpio_irq_startup() calls pinctrl_gpio_direction_input(), which may
sleep while taking the pinctrl core mutex. That makes IRQ startup trip
lockdep when CONFIG_PROVE_LOCKING is enabled.

Move the direction change into irq_request_resources() and keep startup
limited to the ack and unmask operations that are safe in atomic
context.
