These patches add the atlas clocks on Exynos7. It also modifies the
existing cpu clock infrastructure to handle exynos7 differences. These
patches are a pre-requisite for enabling CPUFreq on Exynos7.

Following are the dependencies:
1) arch: arm64: Enable support for Samsung Exynos7 SoC
http://www.spinics.net/lists/linux-samsung-soc/msg38734.html
2) cpufreq: use generic cpufreq drivers for exynos platforms
http://www.spinics.net/lists/linux-samsung-soc/msg39332.html

For testing I have applied the following:
1) mfd: sec: add S2MPS15 PMIC support
https://lkml.org/lkml/2014/10/14/50
2) regulator: s2mps11: add support for S2MPS15 regulators
https://lkml.org/lkml/2014/10/14/52
3) Regulators dt nodes were added in the espresso dts file and I2C channel 4
which has the PMIC on it was tested.
