gpio: Move lock_key into struct gpio_irq_chip
In order to consolidate the multiple ways to associate an IRQ chip with a GPIO chip, move more fields into the new struct gpio_irq_chip. 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>
