gpio: fix sleep-while-atomic in gpiochip_remove

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: 2d7af4c9f02c ("gpiolib: call pin removal in chip removal function")
Fixes: 3c5cd0efbe32 ("gpiolib: provide provision to register pin ranges")
