gpio/pinctrl: make gpio_chip members typed boolean
This switches the two members of struct gpio_chip that were defined as unsigned foo:1 to bool, because that is indeed what they are. Switch all users in the gpio and pinctrl subsystems to assign these values with true/false instead of 0/1. The users outside these subsystems will survive since true/false is 1/0, atleast we set some kind of more strict typing example. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
