[PATCH 170/182] platform: x86: intel-pmic: use gpiochip data pointer

[Linus Walleij <linus.walleij@linaro.org>]

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().

It seems to be unclear who maintains platform/x86, so I'm just
gonna merge this patch into the GPIO tree unless there is a protest
from someone who wants to have a say.
