ARM: pxa: convert incorrect IRQ_TO_IRQ() to irq_to_gpio()
This fixes the failure to register the IRQ_RTCAlrm alarm as a wakeup event. It is misinterpreted as a gpio irq not a PWER bitmask. Fixed this by converting the incorrect IRQ_TO_IRQ() to a correct version of irq_to_gpio(). Reported-by: Nick Bane <nickbane1@gmail.com> Signed-off-by: Eric Miao <eric.y.miao@gmail.com>
