[PATCH V2 1/5] Revert "pinctrl: remove pinctrl_remove_gpio_range"

[Viresh Kumar]

This reverts earlier commit which removed pinctrl_remove_gpio_range(), because
at that time there aren't any more users of that routine. It was removed as the
removal of ranges was done in unregister of pinctrl.

But because we are registering stuff from gpiolib now, we may remove and insert
a gpio module multiple times. So, we need that again.

This is V1 actually. Because it is part of this series, it is marked V2.
