gpio: Export gpiochip_irq_{map,unmap}()
Export these functions so that drivers can explicitly use these when setting up their IRQ domain. Signed-off-by: Thierry Reding <treding@nvidia.com> Acked-by: Grygorii Strashko <grygorii.strashko@ti.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
