Merge branch 'late/dt' into next/dt2

This is support for the ARM Chromebook, originally scheduled
as a "late" pull request. Since it's already late now, we
can combine this into the existing next/dt2 branch.

* late/dt:
  ARM: exynos: dts: cros5250: add EC device
  ARM: dts: Add sbs-battery for exynos5250-snow
  ARM: dts: Add i2c-arbitrator bus for exynos5250-snow
  ARM: dts: Add chip-id controller node on Exynos4/5 SoC
  ARM: EXYNOS: Create virtual I/O mapping for Chip-ID controller using device tree
