There are two ways through which wakeup_en register can be programmed
using gpiolib APIs as shown below. It is seen that in the second case
in _set_gpio_wakeup(), even though bank-suspend_wakeup is updated
correctly, its value is not programmed in wakeup_en register. Fix this.
chip.irq_set_type()-gpio_irq_type()-_set_gpio_triggering()-set_gpio_trigger()
chip.irq_set_wake()-gpio_wake_enable()-_set_gpio_wakeup()
