ARM: s3c24xx: get rid of custom <mach/gpio.h>
This isolates the custom S3C24xx GPIO definition table to <linux/platform_data/gpio-samsung-s3x24xx.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. We also delete the nifty CONFIG_S3C24XX_GPIO_EXTRA stuff. The biggest this can ever be for the S3C24XX is CONFIG_S3C24XX_GPIO_EXTRA = 128, and then for CPU_S3C2443 or CPU_S3C2416 32*12 GPIOs are added, so 32*12+128 = 512 is the absolute roof value on this platform. So we set the size of ARCH_NR_GPIO to this and the GPIOs array will fit any S3C24XX platform, as per pattern from other archs. ChangeLog v2->v3: - Move the movement of the S3C64XX gpio.h file out of this patch and into the follow-up patch where it belongs. ChangeLog v1->v2: - Added an #ifdef ARCH_S3C24XX around the header inclusion in drivers/gpio/gpio-samsung.c as we would otherwise have colliding definitions when compiling S3C64XX. - Rename inclusion guard in the header file.
