gpio: make gpiochip_get_desc() gpiolib-private
As GPIO descriptors are not going to remain unique anymore, having this function public is not safe. Restrain its use to gpiolib since we have no user outside of it. Signed-off-by: Alexandre Courbot <acourbot@nvidia.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
