Convert the machines using the s3c2410 to use the new driver based
on the common clock framework instead of the legacy Samsung clock driver.
As with the s3c244x, machines using the clkout output will need a fixup
from someone with the hardware.

Convert all machines using these cpus to use the ccf clock driver
instead of the legacy Samsung clock implementation.
Some of the more esotheric machines will probably need a fixup, as they
do strange things to the clkout outputs, that I did not really understand
nor have the hardware to check.

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 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.

Now that the only field in struct sys_timer is .init, delete the struct,
and replace the machine descriptor .timer field with the initialization
function itself.
This will enable moving timer drivers into drivers/clocksource without
having to place a public prototype of each struct sys_timer object into
include/linux; the intent is to create a single of_clocksource_init()
function that determines which timer driver to initialize by scanning
the device dtree, much like the proposed irqchip_init() at:

so that we can merge the s3c24 series' directories to the
