Add support for handling IRQs: power button, AC and USB power state
changes. Mask and interrupt bits are shared within one register, which
prevents us to use regmap_irq implementation. New irq_domain is created in
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.

Gave this a try with the peripheral USB port on BeagleBone black,
works fine for me to detect cable events. Will post the musb dsps
related patches after some clean up in few days. Anyways, feel
free to add:
