Subject: [PATCH] ARM: s3c64xx: get rid of custom <mach/gpio.h>

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.
