Without this, the PMC continually detects an interrupt when the PMU_IRQ
line is high, causing the tps6686x IRQ handler thread to hog an entire
CPU.

This change was originally written by Wei Ni [off-list ref] for Seaboard
in the ChromeOS kernel.

Long-term, this should probably be moved into some kind of PMU driver,
or perhaps integrated into the GPIO/IRQ/pinmux system?

Olof, is this change OK for inclusion? Or, should we create some kind
of PMU driver and interrupt controller to solve this?

I'm OK with it going in now as it is, but as we move to more things to
device-tree, having a common piece of code that does it based on
properties there would make sense. Today I think every single board
needs it.

I'll pick up the patch and push it out later today.
