Subject: [PATCH 1/6] Input: mc13783-pwrbutton: fix irq mixup

The mfd mc13xxx interrupt handling was migrated to regmap with commit
10f9edaeaa30 ("mfd: mc13xxx: Use regmap irq framework for interrupts").
As a consequence, button_irq() will get called with virtual irq instead
of chip-internal irq now. Add wrappers for the three supported interrupts.
