For Exynos4x12 platforms, add CPU operating points (using
opp-v2 bindings) and CPU regulator supply properties for
migrating from Exynos specific cpufreq driver to using
generic cpufreq driver.
Based on the earlier work by Thomas Abraham.

dw-mmc controller can support multiple slots.
But, there are no use-cases anywhere. So we don't need to support the
slot-node for dw-mmc controller.
And "supports-highspeed" property in dw-mmc is deprecated.
"supports-highspeed" property can be replaced with "cap-sd/mmc-highspeed".

All SoCs from Exynos4x12 series contain the MSHC block, so its node can
be located in exynos4x12.dtsi. In addition, missing clock specifiers
are added, generic SoC attributes are moved from board dts files
to common dtsi file of SoC family and the node is renamed to a more
generic name to follow node naming recommendations.

These are mostly new device tree bindings for existing drivers, as well
as changes to the device tree source files to add support for those
devices, and a couple of new boards, most notably Samsung's Exynos5
based Chromebook.
The changes depend on earlier platform specific updates and touch
the usual platforms: omap, exynos, tegra, mxs, mvebu and davinci.
