media: i2c: adv7180: Extend match support for OF tables
The driver has an OF match table, still, it uses an ID lookup table for retrieving match data. 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.
