Subject: gpio: unregister gpiochip device before removing it

From: Johan Hovold <[email protected]>

commit 01cca93a9491ed95992523ff7e79dd9bfcdea8e0 upstream.

Unregister gpiochip device (used to export information through sysfs) before removing it internally. This way removal will reverse addition.
