Subject: [PATCH] mfd: arizona: Propagate irq_wake through to parent IRQ

If one of the internal Arizona IRQs is set as a wake source this needs
to be propogated back to the actual IRQ line that the Arizona device is
attached to.

Just thought I would resend this one on its own as it is a good
bug fix and didn't need to depend on the other extra callbacks patch.
And it would be good to get it in whilst I work on the IRQ stuff.
