ARM: make mach/gpio.h headers optional
Most platforms don't need mach/gpio.h and it prevents multi-platform kernel images. Add CONFIG_NEED_MACH_GPIO_H and make platforns select it if they need gpio.h. This is platforms that define __GPIOLIB_COMPLEX or have lots of implicit includes pulled in by mach/gpio.h. at91 and omap have gpio clean-up pending and can drop CONFIG_NEED_MACH_GPIO_H once that is in.
