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 v2:
3. uses the new compatible strings introduced along with adding
support for Exynso5420.
