ARM: dts: exynos: Add support of Bus frequency using VDD_INT for exynos5422-odroidxu3
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 bandwidth for AMBA AXI bus. The WCORE bus bus is parent device in INT block using VDD_INT.
