Currently, the driver is working on the assumption that an I2C device registered via OF will always match a legacy I2C device ID. The correct approach is to have an OF device ID table using i2c_get_match_data() if the devices are registered via OF/ID. Unify the OF/ID table by using struct adv7180_chip_info as match data for both these tables and replace the ID lookup table for the match data by i2c_get_match_data(). While at it, remove the trailing comma in the terminator entry for the OF table making code robust against (theoretical) misrebases or other similar things where the new entry goes _after_ the termination without the compiler noticing.
