From: Basavaraj Natikar <Basavaraj.Natikar@xxxxxxx> commit acd47b9f28e55b505aedb842131b40904e151d7c upstream. Enable/disable power management wakeup mode, which is disabled by default. enable_irq_wake enables wakes the system from sleep. Hence added enable/disable irq_wake to handle wake-up interrupt.
