ARM: 7033/1: mach-u300: break out GPIO driver specifics The <mach/gpio.h> file is included from upper directories and deal with generic GPIO and gpiolib stuff. Break out the platform and driver specific defines and functions into its own header file.

pinctrl/coh901: retire ancient GPIO block versions As the non-U335 U300 variants are retired from the ARM tree, also delete the pinctrl driver codepaths for these variants. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>

ARM: 7083/1: rewrite U300 GPIO to use gpiolib This rewrites the U300 GPIO so as to use gpiolib and struct gpio_chip instead of just generic GPIO, hiding all the platform specifics and passing in GPIO chip variant as platform data at runtime instead of the compiletime kludges. As a result <mach/gpio.h> is now empty for U300 and using just defaults.

pinctrl: spawn U300 pinctrl from the COH901 GPIO This solves the riddle on how the U300 pin controller shall be able to reference the struct gpio_chip even though these are two separate drivers: spawn the pinctrl child from the GPIO driver and pass in the struct gpio_chip as platform data. In the process we rename the U300 "pinmux-u300" to "pinctrl-u300" so as not to confuse. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
