This patch adds the ISP I2C bus controller driver files. Creating a standard I2C bus adapter, even if the driver doesn't actually communicate with the hardware and it is instead controlled by the ISP firmware running on the Cortex-A5, allows to use standard hardware description in the device tree. As the sensor would have actually had a standard V4L2 sub-device driver run on the host CPU. This approach allows to adapt the driver with a relatively small effort should the Imaging Subsystem architecture change so that the I2C bus is handled by the host's CPU OS, rather than the internal FIMC-IS ARM CPU firmware. The image sensor driver could be a standard I2C client driver, as in case of most existing image sensors.
