This patch adds the bus nodes using VDD_INT for Exynos5433 SoC.
Exynos5433 has the following AMBA AXI buses to translate data
between DRAM and sub-blocks.
Following list specify the detailed correlation between sub-block and clock:
- CLK_ACLK_G2D_{400|266} : Bus clock for G2D (2D graphic engine)
- CLK_ACLK_MSCL_400 : Bus clock for MSCL (Memory to memory Scaler)
- CLK_ACLK_GSCL_333 : Bus clock for GSCL (General Scaler)
- CLK_SCLK_JPEG_MSCL : Bus clock for JPEG
- CLK_ACLK_MFC_400 : Bus clock for MFC (Multi Format Codec)
- CLK_ACLK_HEVC_400 : Bus clock for HEVC (High Efficient Video Codec)
- CLK_ACLK_BUS0_400 : NoC(Network On Chip)'s bus clock for PERIC/PERIS/FSYS/MSCL
- CLK_ACLK_BUS1_400 : NoC's bus clock for MFC/HEVC/G3D
- CLK_ACLK_BUS2_400 : NoC's bus clock for GSCL/DISP/G2D/CAM0/CAM1/ISP
