[PATCH v4 0/8] arch: arm64: enable support for Samsung Exynos7 SoC

[Naveen Krishna Chatradhi <ch.naveen@samsung.com>]

Changes since v3:
- Removed aliases for serial controllers from dtsi file and moved it
  into board specific dts file as suggested by Arnd.
- Based this series on Robert Richter's patches for adding vendor
  device tree sub-directories for arm64.

This patchset supports new Exynos7 Samsung SoC based on Cortex-A57.
Exynos7 is a System-On-Chip (SoC) that is based on 64-bit
ARMv8 RISC processor.

The following patches are tested based on Kgene's for-next tree.
