[PATCH V3 4/5] mfd: palmas: support IRQ inversion at the board level

[Lee Jones]

> From: Stephen Warren <swarren at nvidia.com>
> 
> Implement the new DT property ti,irq-externally-inverted, and add an
> equivalent platform data field to match. This allows the driver to
> correctly automatically configure the IRQ output polarity when the board
> or SoC contains an inverter between the Palmas IRQ output and IRQ
> controller input.

> v3:
> * Use an IRQD flag to represent the data, rather than a custom DT property.
> v2:
> * Split V1's patch 1/2 into separate patches 1/3 and 2/3.

Looks good to me. Let me know how you want to deal with this. I'm
happy to create an immutable branch for everyone to pull from.
