When refactoring and breaking out the includes for the
machine-specific GPIO configuration, two files were created
in <linux/platform_data/gpio-samsung-s3c[24|64]xx.h>, but as
that namespace shall be used for defining data exchanged
between machines and drivers, using it for these broad macros
and config settings is wrong.

Move the headers back into the machine-local
<mach/gpio-samsung.h> file and think about the next step.

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.

Change the code setting a range of GPIO pins' configuration and
pull state to use the recently introduced s3c_gpio_cfgall_range().
