Subject: [PATCH v12 4/4] ARM: dts: Exynos5420: Add device nodes for TMU blocks

Exynos5420 SoC has per core thermal management unit.
5 TMU channels 4 for CPUs and 5th for GPU.

This patch adds the device tree nodes to the DT device list.

Nodes carry the misplaced second base address and the second
clock to access the misplaced base address.

Changes since v11:
  changed the secondary clock name to "tmu_triminfo_apbif"
from "tmu_apbif_triminfo"

Changes since previous version:
1. used lables instead of comment lines
2. pass the same clock as trimfo_apbif clock for TMU channel 2
3. Fixed a coding style problem pointed by Tomasz
