In a multiplatform kernel, each initcall is run regardless
of the platform it is meant for, so it must not attempt to
access SoC-specific registers.
This adds 'if (soc_is_s3c64xx)' to all initcalls that are
specific to the s3c64xx platform, to prevent them from breaking
other platforms once we can build them into a combined kernel.

Since S5PV210 now has a complete clock driver using Common Clock
Framework, there is no reason to keep the old code. Remove it together
with the whole legacy Samsung-specific clock framework which no longer
has any users.

These could not be part of the first cleanup branch, because they either
came too late in the cycle, or they have dependencies on other branches.
Important changes are:
* The integrator platform is almost multiplatform capable after
some reorganization (Linus Walleij)
* Minor cleanups on Zynq (Michal Simek)
* Lots of changes for Exynos and other Samsung platforms, including
further preparations for multiplatform support and the clocks bindings
are rearranged.

These cleanup patches are mainly move stuff around and should all
be harmless. They are mainly split out so that other branches can
be based on top to avoid conflicts.
Notable changes are:
* We finally remove all mach/timex.h, after CLOCK_TICK_RATE is no
longer used. (Uwe Kleine-König)
* The Qualcomm MSM platform is split out into legacy mach-msm and
new-style mach-qcom, to allow easier maintainance of the new
hardware support without regressions. (Kumar Gala)
* A rework of some of the Kconfig logic to simplify multiplatform
support (Rob Herring)
* Samsung Exynos gets closer to supporting multiplatform (Sachin
Kamat and others)
* mach-bcm3528 gets merged into mach-bcm (Stephen Warren)
* at91 gains some common clock framework support (Alexandre Belloni,
Jean-Jacques Hiblot and other French people).

If CONFIG_SERIAL_SAMSUNG is disabled, we run into build errors
with some samsung platforms. This adds a couple of #ifdef
statements to hopefully deal with this more gracefully.
