This patch set adds the atlas clock hierarchy 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.

This  patch set has been tested on next-20150202 with samsung
clk tree (for-v3.20/clk/next branch) merged.

Following are the dependencies:
1) cpufreq: use generic cpufreq drivers for exynos platforms (v12)

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.
