This patch adds all nodes for camera devices on example Exynos4412 SoC based board. This is all what's required in the board dts file to enable rear facing camera (S5C73M3 sensor). The aliases node contains entries required for the camera processing data path entity drivers. The sensor nodes use standard port/remote-endpoint nodes convention. Internal SoC links between entities are not specified this way and are coded in the driver instead, as it seemed more reasonable. The S5C73M3 sensor uses two control buses: I2C and SPI. There are two, i2c_0 and spi_1 bus controller child nodes assigned to it.
