Move the code for the pwm-clock into plat-samsung, as it is common to
all Samsung SoCs.

This patch makes clk_default_setrate and clk_ops_def_setrate available
to code outside plat-samsung clock code.

If there is no source register defined, do not register a clksrc
clock with a valid .set_parent in the ops.

Add s3c_register_clocks() to register an array of clocks, printing
an error message if there is a problem. Replace all points in the code
where this could be used.

If the reg_div field is not set, then do not register clk_ops with the
get/set/round rate calls as these will fail to work.

This is the core implementation of the clock code for all Samsung based
SoCs, so move it to arch/arm/plat-samsung (the clock.h file has already
been moved).

Since the file is built for every Samsung SoC, no changes are needed to the
Kconfig system.

The new code calls the clock setup code on registration which
can be before the clock system has been fully initialised. The
following code re-does this setup at the end of the clock
registration and thus we get two printings.

Update the calls to only print on the last pass or when doing
the necessary resume work.

Reduce the size of struct clk by 12 bytes and make defining clocks with
common implementation functions easier by moving the set_rate, get_rate,
round_rate and set_parent calls into a new structure called 'struct clk_ops'
and using that instead.

This change does make a few clocks larger as they need their own clk_ops,
but this is outweighed by the number of clocks with either no ops or having
a common set of ops.

Update all the users of this.

Add a core for the clksrc clock implementation, which is found in many of
the newer Samsung SoCs into plat-samsung.

Move the <plat/clock.h> header to plat-samsung where it can be used by all
the platforms, and readies it for the next round of clock updates where
the clock code will be amalgamated.

We inted to re-organise the plat-s3c/plat-s3c24xx/plat-s3c64xx into a
more generic plat-samsung with less code in the other plat- directories
to make it easier to port new devices and try and clear up some of the
naming issues with newer devices.

Start by creating a small arch/arm/plat-samsung with no actuall code in
so we can move items in as we process them.

Add this to arch/arm to allow it to build things once support is added.
