[PATCH v3 0/6] Add minimal Exynos8855 SoC support

[Alim Akhtar]

This series adds initial support for the Exynos8855 SoC and also
initial SMDK board support. 

Exynos8855 is octa-core CPUs, a combination of Cortex-A720 and Cortex-A520,
arranged in 3 clusters. And other peripheral for mobile application.

This initial support consists of CPUs, pinctrl and related nodes
needed for initial kernel boot.

With these patches, kernel can boot using initramfs till file system mounts.

More platform support will be added in near future, clock driver to go next.

Changes since v2:
* Addressed review comments from Peter Griffin and Krzysztof.
* Updated uses of GS101 MACROS for pinctrl driver
* Documented  wakeup interrupt binding
* Rebased on latest Linux-next
 
Chanegs since v1:
* Fixed some of the review comments by Sashiko [1]
* Dropped serial node, will be added once clock support is available
* Dropped wkup interrupt for CMGP block, will be added later
