pinctrl: airoha: fix IRQ mask/unmask code

Browse source

When using IRQCHIP_IMMUTABLE, airoha_irq_unmask() must manually call
gpiochip_enable_irq() and airoha_irq_mask() must call
gpiochip_disable_irq(). Without these calls, gpiolib never sets the
GPIOD_FLAG_IRQ_IS_ENABLED bit. Because this bit is missing,
gpiod_direction_output() will not realize the pin is actively used
as an interrupt.
