    pinctrl: intel: Clear interrupt status in mask/unmask callback

    Commit a939bb57cd47 ("pinctrl: intel: implement gpio_irq_enable") was
    added because clearing interrupt status bit is required to avoid
    unexpected behavior.

    Turns out the unmask callback also needs the fix, which can solve weird
    IRQ triggering issues on I2C touchpad ELAN1200.
