[PATCH 7/7] ARM: dts: Add support of Bus frequency using VDD_INT for exynos5422-odroidxu3

[Chanwoo Choi <cw00.choi@xxxxxxxxxxx>]

This patch adds the bus device tree nodes for INT (Internal) block
to enable the AMBA bus frequency scaling and add the NoC (Network on Chip)
Probe Device Tree node to measure the bandwidht for AMBA AXI bus.

The WCORE bus bus is parent device in INT block using VDD_INT.
