exynos: Move pmu driver to driver/soc folder and add exynos7 support

Hi Pankaj,

If you possible, could you add me to mailing list on the next patchset? because I'll support PMU for Exynos5433, too.

Best Regards,
Chanwoo Choi

This patch series [1 - 6] performs,

1) Moves pmu driver to driver/soc/samsung folder. This is needed as exynos7 is an arm64 based platform and hence PMU driver should be in driver folder. Some discussion happened about this in the v1 version. Finally adding it in driver/soc folder as it too SoC specific and not a general driver. Entire discussion can be found here (A).
2) Add exynos7 PMU support.
3) Enables the driver for 32bit arm exynos platforms.

TODO: There is some suggestion to split the PMU data for 32 bit and 64 bit Exynos SOC. This can be implemented as a separate optimization patches. Submitting this version without much change from previous version as the merge window is near.

Change from V4:
* Added a new configuration structure for u32 values in patch 4.
* Rebased on Kukjin for-next tree.

Changes from V3:
* Fixed Kconfig as per Russell feedback
* Rebased the series against Pankaj SoC restart consolidation patches (D) as per Kukjin request.
* Link to V3 can be found here (C)

Changes from V2:
* Added review comment changes suggested by Pankaj.
* Removed mfd client support in this patch series. This will be added later in the power domain patch series.
* Link to V2 can be found here (B)

Changes from V1:
* Move pmu driver in driver/soc/samsung folder
* Removed the power domain features. They will posted as a separate series.
* Added exynos7 PMU support.
* Link to v1 can be found here (A)

This complete patch series is rebased on Kukjin for-next tree.
