pinctrl/ARM: move GPIO and pinctrl deps to device tree
This gets the GPIO ranges out of the driver and into the device tree where they belong. Standard DT bindings already exist for this. Since no systems with this are deployed we can just augment all device trees and the drivers at the same time and simplify the world. This also defines the array of GPIO chips related to the pin controller. Cc: arm@kernel.org Acked-by: Olof Johansson <olof@lixom.net> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
