Remove the definitions we've deleted in the previous updates to the
clksrc_clk for arch/arm/plat-s5pc1xx/include/plat/regs-clock.h.

Added comments about the removal to the clock header since we only need
these defines in one place (and they've now been removed there) we get
rid of them from the header.

This script is used to change the old style clksrc_clk as originally

Remove the individual 'struct clksrc_clks' and place them into an array
so that we can simply use s3c_register_clksrcs to register tham all in one
go.

Since the spdif clock relies on the audio clock, move the audio clocks
into their own arrary.

Thanks to  Marek Szyprowski for testing and pointing out the four clocks
what where missed from the clock list.

Remove the copy of the old s3c64xx struct clksrc_clk and use the new one
in plat-samsung. This eliminates a bug in the set_parent() call where it
failed to set the clk->parent after sucesfully updating the clock.

seperately.

Add a common entry-macro-vic2.S for systems where there are two VICs
so that the machine or platform directories just need to setup the
correct information before including <asm/entry-macro-vic2.S> into
their own entry-macro.S file.

Since this code is from the S3C64XX project, we update the S3C64XX
machine entry code to use this new header.

Move the handling for the UART interrupts out of the s3c64xx specific
code and into plat-samsung so that it can be used by all implementations
that need it.

Move the VIC based timer interrupt handling out of plat-s3c64xx and
into plat-samsung to be re-used for other systems. This also reduces
the code size as we now have a common init routine and use the irq_desc
to store the interrupt number of the timer.

If the reg_div field is not set, then do not register clk_ops with the

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.

The individually named clocks are all static to the code
and thus can be compressed into a single array and then
the array can be referenced. This removes the need for
a seperate array of pointers to clocks.

Fix a minor problem of re-initialising the pointers in
s3c6400_set_clksrc() as this is also called by the cpufreq
code. Move these initialisations to the code that does the
registration.

Remove the four fields from clksrc_clk.clk which are always the same
