gpiochip_get_data() doesn't exist in 4.4.

I've cherry-picked commits b08ea35a3296 "gpio: add a data pointer to
gpio_chip", 0cf3292cde22 "gpio: Add devm_ apis for gpiochip_add_data and
gpiochip_remove", and 3988d663c02f "gpiolib: Fix a WARN_ON that can
never trigger" before this.  But you should have included them in this
patch series.

Ben.
