Let's keep the file ordered. Best regards, Krzysztof

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.
