Add support for handling IRQs: power button, AC and USB power state

order to add interrupt handling for each tps65217's subsystem. IRQ
resources have been added for charger subsystem to be able to notify
about
AC and USB state changes.

Just curious Why not use a regmap_irq?


tps65217 has IRQ mask and status bits in a single register. regmap_irq
works in case of two different registers (one mask, one status), but
with the same layout of mask and status bits in both.


Thanks for the info.
