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 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.

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.

The file arch/arm/include/asm/cpu.h needs to include 'linux/cpu.h' to
meet its dependency. Otherwise when using "struct cpuinfo_arm" and
including just 'asm/cpu.h' throws below error -

To fix this  otherway, one can also include both linux/cpu.h and
asm/cpu.h but it shoudn't be that way.  So this patch fixes this by
including the linux/cpu.h in asm/cpu.h, so that including alone

as the referenced variable 'isa_dma_bridge_buggy' in asm/dma.h is
enclosed by the CONFIG_ISA_DMA_API conditional all configs without this
setting fail to build.

I'm not sure wether moving the condition is the right way to solve the

This change adds in some missing clocks that were needed as a result
of 526505... (OMAP1 clock: convert mach-omap1/clock.h to
mach-omap1/clock_data.c).  Prior to this, it was just assumed that
these clocks existed for all devices, and it was used directly instead
of calling it out with a clock_get call or similar.  So, not having
the CK_7XX meant these clocks weren't being used anymore for omap 7xx
devices, which broke things badly.
