    Add level active IRQ support to regmap-irq irqchip. Change breaks
    existing regmap-irq type setting. Convert the existing drivers which
    use regmap-irq with trigger type setting (gpio-max77620) to work
    with this new approach. So we do not magically support level-active
    IRQs on gpio-max77620 - but add support to the regmap-irq for chips
    which support them =)
    
    We do not support distinguishing situation where HW supports rising
    and falling edge detection but not both. Separating this would require
    inventing yet another flags for IRQ types.
