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().

AVR32 folks: please ACK this patch so I can take it through the
GPIO tree.
BTW: consider tidying up and moving this driver to drivers/pinctrl
and implement the right pin control interfaces for AVR32 ...
thanks.
