Johan Hovold 72d8d4dd17 gpio: fix sleep-while-atomic in gpiochip_remove ...

commit 6798acaa01 upstream.

Move direct and indirect calls to gpiochip_remove_pin_ranges outside of
spin lock as they can end up taking a mutex in pinctrl_remove_gpio_range.

Note that the pin ranges are already added outside of the lock.

Fixes: 9ef0d6f762 ("gpiolib: call pin removal in chip removal function")
Fixes: f23f1516b6 ("gpiolib: provide provision to register pin ranges")
