Fix building of exynos defconfig with disabled PM_SLEEP:
CONFIG_PM_SLEEP=n
CONFIG_PM_SLEEP_SMP=n
CONFIG_SUSPEND=n
by moving functions for power up/down of CPU and cluster to platsmp.c
The build error messages:
arch/arm/mach-exynos/built-in.o: In function `exynos_boot_secondary':
arch/arm/mach-exynos/platsmp.c:111: undefined reference to `exynos_cpu_power_state'

arch/arm/mach-exynos/platsmp.c:116: undefined reference to `exynos_cpu_power_state'
make: *** [vmlinux] Error 1

Changes since v1:
1. Use different solution - just move the power up/down functions to a
common place instead of adding stubs in common.h. Suggested by Tomasz
Figa.

Applied, thanks.
Bart, I think this is better at this moment to fix the build breakage
with disabling PM...if you have any comments, please let me know.

To fix PM_SLEEP=n build itself (with ARM_EXYNOS_CPUIDLE=n) Krzysztof's
patch is not enough and patch [1] is also needed (this patch is very
simple so I think that it is okay for v3.16).
For PM_SLEEP=n and ARM_EXYNOS_CPUIDLE=y config more changes are needed
and they are contained in patch [2] (please note that this patch depends
on patch [3] from Tomasz Figa which was redone recently into [4] so my
patch also needs to be refreshed). However if you think that this would
result in too much changes for v3.16 kernel we can make ARM_EXYNOS_CPUIDLE
select (or depend on) PM_SLEEP for now and fix the issue completely later
in v3.17 kernel.

Hmmm, I now see that you've applied Krzysztof's patch for v3.17 not v3.16.
In that case how do you want to deal with PM_SLEEP=n build breakages for
v3.16 and what do you mean with "fix the build breakage with disabling PM"?

Just a bit of explanation:
The PM_SLEEP=n build breakages show up on automated build tests done by
various people. Minimal fixes for them (Krzysztof's patch + patch [1] +
making ARM_EXYNOS_CPUIDLE depend on PM_SLEEP temporally) are really obvious
and should be pretty safe so it would be great to have them in v3.16.
If that is not possible lets fix the issue completely early in v3.17 cycle.

Okay, so Krzysztof's patch was posted in pull request to Olof on Saturday
and merged already for v3.17. In that case I will just refresh my patches
and resubmit later. Sorry for all the noise.
