This makes the driver use the data pointer added to the gpio_chip
to store a pointer to the state container instead of relying on
container_of().

Dmitry: please ACK this so I can take it through the GPIO tree.

I just went in and edited the commit. No other change so not resending,
OK?

First I thought this textstring thing was minor but now I'm fixing it up,
why not.
