PM: wakeirq: Set IRQF_NO_AUTOEN when requesting the IRQ

PM: wakeirq: Set IRQF_NO_AUTOEN when requesting the IRQ

request_irq() after setting IRQ_NOAUTOEN as below
irq_set_status_flags(irq, IRQ_NOAUTOEN);
request_irq(dev, irq...);
can be replaced by request_irq() with IRQF_NO_AUTOEN flag.

This change is just to simplify the code, no actual functional
changes.
