gpio: mvebu: add wake-up interrupt support

Browse source

Implement wake IRQ support for the mvebu GPIO controller:

- Replace unused irqbase field with bank_irq[4] to store per-bank
  IRQ numbers for use in the wake-up callback.
- Add mvebu_gpio_set_wake_irq() that forwards enable_irq_wake /
  disable_irq_wake to the correct parent IRQ based on hwirq.
- Set IRQCHIP_SET_TYPE_MASKED and IRQCHIP_MASK_ON_SUSPEND flags
  on both level and edge chip types.
- Set IRQ_GC_INIT_NESTED_LOCK for the nested irq domain.
- Add missing <linux/interrupt.h> include.
