This isolates the custom S3C64xx GPIO definition table to <linux/platform_data/gpio-samsung-s3x64xx.h> as this is used in a few different places in the kernel, removing the need to depend on the implicit inclusion of <mach/gpio.h> from <linux/gpio.h> and thus getting rid of a few nasty cross-dependencies. Also delete the CONFIG_SAMSUNG_GPIO_EXTRA stuff. Instead roof the number of GPIOs for this platform: First sum up all the GPIO banks from A to Q: 187 GPIOs. Add the 16 "board GPIOs" and the roof for SAMSUNG_GPIO_EXTRA, 128, so in total maximum 187+16+128 = 331 GPIOs, so let's take the same roof as for S3C24XX: 512. This way we can do away with the GPIO calculation macros for GPIO_BOARD_START, BOARD_NR_GPIOS and the definition of ARCH_NR_GPIOS.
